Active Directory 2003 Interview Question and Answer

Active Directory 2003 Interview Question and Answer :-

1) Logical Diagram of Active Directory? What is the difference between child domain & additional domain server?

A) Active directory contains forest, tree, domain and its child domain. Child domian is comes under parent domain and it shares the name space, its names space append the parent domain name. Addtional domain controller is the copy of main domain controller and its for load balancing and fault tolarance.

 2) What are the Port numbers ?

A)

FTP : 21,TELNET : 23 , SMTP: 25 , DNS : 53 , DHCP : 67 , KERBEROS : 88 , POP3 : 110 , NNTP : 119 , IMAP : 143 ,

SNMP :  161,LDAP: 389,SSL:  443,MS-DS-AD: 445, RPC: 530,  LDAP-S: 636,IMAP-S: 993 ,  POP-S: 995, Lotus Notes: 1352,

Sametime: 1533, MS-PPTP:1723,  MS-RDP: 3389

3) What is Kerberos? Which version is currently used by Windows? How does Kerberos work?

A) Kerberos is the user authentication used in Win2000 and Win2003 Active Directory servers

Kerberos version is 5.0. Port is: 88. It’s more secure and encrypted than NTLM (NT authentication)

Kerberos makes use of a trusted third party, termed a Key Distribution Center (KDC), which consists of two logically separate parts: an Authentication Server (AS) and a Ticket Granting Server (TGS). Kerberos works on the basis of “tickets” which serve to prove the identity of users.

The KDC maintains a database of secret keys; each entity on the network – whether a client or a server – shares a secret key known only to itself and to the KDC. Knowledge of this key serves to prove an entity’s identity. For communication between two entities, the KDC generates a session key which they can use to secure their interactions.

 4) What are FSMO Roles? List them.

A) Flexible Single Master Operation Roles (FSMO) roles are server roles in a Forest

There are five types of FSMO roles

  1. Domain Naming Master – Forest Wide Roles
  2. Schema Master – Forest Wide Roles
  3. RID Master – Domain Wide Roles
  4. PDC Emulator – Domain Wide Roles
  5. Infrastructure Master – Domain Wide Roles

Domain Naming Master : Adding / Changing / Deleting any Domain in a forest it takes care

Schema Master : It maintains structure of the Active Directory in a forest.

RID Master : It assigns RID and SID to the newly created object like Users and computers. If RID master is down (u can create security objects upto RID pools are available in DCs) else u can’t create any object one its down

PDC emulator : It works as a PDC to any NT BDCs in your environment. It works as Time Server (to maintain same time in your network). It works to change the passwords, lockout, etc.

Infrastructure Master : This works when we are renaming any group member ship object this role takes care.

5) Describe the lease process of the DHCP server .

A) A DHCP lease is the amount of time that the DHCP server grants to the DHCP client permission to use a particular IP address. A typical server allows its administrator to set the lease time.

It’s a four-step process consisting of

(a) DHCP discovery,

(b) DHCP offer,

(c) DHCP Request and

(d) DHCP Acknowledgement.

6) WHAT IS THE FUNCTION OF DHCP?

A) Providing IP address dynamically

8) What is forest.

A) It is a collection of trees. Tree is nothing but collection of domains which is having same name space. Domain contains domain controllers.

Forest — Tree — Domain.

 9) What is Active Directory?

A)     Active Directory is a network-based object store and service that locates and manages resources, and makes these resources available to authorized users and groups. An underlying principle of the Active Directory is that everything is considered an object—people, servers, workstations, printers, documents, and devices. Each object has certain attributes and its own security access control list (ACL).

10) Where are the Windows NT Primary Domain Controller (PDC) and its Backup Domain Controller (BDC) in Server 2003?

A) The Active Directory replaces them. Now all domain controllers share a multimaster peer-to-peer read and write relationship that hosts copies of the Active Directory.

11) How long does it take for security changes to be replicated among the domain controllers?

A)     Security-related modifications are replicated within a site immediately. These changes include account and individual user lockout policies, changes to password policies, changes to computer account passwords, and modifications to the Local Security Authority (LSA).

12) What is Active Directory schema?

A) The Active Directory schema contains formal definitions of every object class that can be created in an Active Directory forest it also contains formal definitions of every attribute that can exist in an Active Directory object. Active Directory stores and retrieves information from a wide variety of applications and services. So that it can store and replicate data from a potentially infinite variety of sources, Active Directory standardizes how data is stored in the directory. By standardizing how data is stored, the directory service can retrieve, update, and replicate data while ensuring that the integrity of the data is maintained.

Schema master is a set of rules which is used to define the structure of active directory. It contains definitions of all the objects which are stored in AD. It maintains information and detail information of objects.

13) How will you backup Active Directory?

A)     Take the system state data backup. This will backup the active directory database. Microsoft recommend only Full backup of system state database

14) What are the contents of System State backup?

A)     The contents are
Boot files, System files, Active directory (if its done on DC), SYSVOL folder(if it done on DC),
Certificate service ( on a CA server), Cluster database ( on a cluster server), Registry
Performance counter configuration information, Component services class registration database

15) Compare Active directory & SAM?

Windows NT Windows 2000
Single-master   replication is used via PDCs and BDCs. Multimaster   replication is used via DCs.
Domain is the   smallest unit of partitioning. Domain is the   smallest unit of partitioning.
Domain is the   smallest unit of authentication. OU is the   smallest unit of authentication.
Domain is the   smallest unit of policy (system policies). OU is the   smallest unit of policy (group policy objects).
Domain is the   smallest unit of security delegation/administration. A property of   an object is the smallest unit of security delegation/administration.
NetBIOS   broadcasts as primary browsing and connection mechanism. TCP/IP connections   to Active Directory as primary browsing and connection mechanism.
WINS or LMHOSTS   required for effective browsing. DNS and Active   Directory required for effective browsingWINS required   for older clients.
Object is the   smallest unit of replication. Property is the   smallest unit of replication.
Maximum   recommended database size for SAM is 40 MB. Maximum   database size for Active Directory is 70 TB.
Maximum   effective number of users is 40,000 (if you accept the recommended 40 MB   maximum). Maximum number   of users (objects) in one domain is between one and two millionMaximum number   of users (objects) in one forest is 10 million.
Four domain   models (single, single-master, multimaster, complete-trust) required to solve   admin-boundary and user-limit problems being per domain. No domain   models required as the complete-trust model is implemented.One-way trusts   can be implemented manually.
Schema is not   extensible. Schema is fully   extensible.

16) What is the default domain functional level in Windows Server 2003?

A) The four domain functional levels are:

Windows 2000 Mixed, Windows 2000 Native, Windows Server 2003 Interim, Windows Server 2003, Windows 2000 Mixed

When you configure a new Windows Server 2003 domain, the default domain functional level is Windows 2000 mixed. Under this domain functional level, Windows NT, 2000, and 2003 domain controllers are supported. However, certain features such as group nesting, universal groups, and so on are not available.

Windows 2000 Native
Upgrading the functional level of a domain to Windows 2000 Native should only be done if there are no Windows NT domain controllers remaining on the network. By upgrading to Windows 2000 Native functional level, additional features become available including: group nesting, universal groups, SIDHistory, and the ability to convert security groups and distribution groups.

Windows Server 2003 Interim

The third functional level is Windows Server 2003 Interim and it is often used when upgrading from Windows NT to Windows Server 2003. Upgrading to this domain functional level provides support for Windows NT and Windows Server 2003 domain controllers. However, like Windows 2000 Mixed, it does not provide new features.

Windows Server 2003
The last functional level is Windows Server 2003. This domain functional level only provides support for Windows Server 2003 domain controllers. If you want to take advantage of all the features included with Windows Server 2003, you must implement this functional level. One of the most important features introduced at this functional level is the ability to rename domain controllers

17) In which domain functional level, we can rename domain name?

A) All domain controllers must be running Windows Server 2003, and the Active Directory functional level must be at the Windows Server 2003. Yes u can rename the domain in windows server 2003

18) Which is the default protocol used in directory services?

A) Light weight Directory Access Protocol (LDAP)

19) What is a site?

A) Sites: one or more well-connected highly reliable and fast TCP/IP subnets. A site allows administrator to configure active directory access and replication topology to take advantage of the physical network.

20) Which is the command used to remove active directory from a domain controller?

A) “dcpromo” in command prompt to add/remove active directory but first ADC should be removed before DC if we want to remove DC first then check this server is last domain controller in domain.

Removing Active Directory:

1. If we want to remove Active Directory then we will use command……DCPROMO

2. If some one deleted parent domain and we want to remove from child domain then we will use command… DCPROMO /FORCEREMOVAL

Note: – One should not remove parent domain first. He should start from bottom means child domain and after that its parent and so on.

21) What is trust?

A) To allow users in one domain to access resources in another, AD uses trust. Trust is automatically produced when domains are created. The forest sets the default boundaries of trust, not the domain, and implicit trust is automatic. As well as two-way transitive trust, AD trusts can be shortcut (joins two domains in different trees, transitive, one- or two-way), forest (transitive, one- or two-way), realm (transitive or nontransitive, one- or two-way), or external (nontransitive, one- or two-way) in order to connect to other forests or non-AD domains. AD uses the Kerberos V5 protocol, although NTLM is also supported and web clients use SSL/TLS.

22) What is the file that’s responsible for keep all Active Directory database?

A) NTDS.DIT. default size : 40 MB

23) What snap-in administrative tools are available for Active Directory?

A) Active Directory Domains and Trusts Manager, Active Directory Sites and Services Manager, Active Directory Users and Group Manager, Active Directory Replication (optional, available from the Resource Kit), Active Directory Schema Manager (optional, available from adminpak)

24) What types of classes exist in Windows Server 2003 Active Directory?

A) Structural class: The structural class is important to the system administrator in that it is the only type from which new Active Directory objects are created. Structural classes are developed from either the modification of an existing structural type or the use of one or more abstract classes.

Abstract class: Abstract classes are so named because they take the form of templates that actually create other templates (abstracts) and structural and auxiliary classes. Think of abstract classes as frameworks for the defining objects.

Auxiliary class: The auxiliary class is a list of attributes. Rather than apply numerous attributes when creating a structural class, it provides a streamlined alternative by applying a combination of attributes with a single include action.

88 class: The 88 class includes object classes defined prior to 1993, when the 1988 X.500 specification was adopted. This type does not use the structural, abstract, and auxiliary definitions, nor is it in common use for the development of objects in Windows Server 2003 environments.

25) How do you delete a lingering object?

A) Windows Server 2003 provides a command called Repadmin that provides the ability to delete lingering objects in the Active Directory.

26) What is Global Catalog?

A) The Global Catalog authenticates network user logons and fields inquiries about objects across a forest or tree. Every domain has at least one GC that is hosted on a domain controller. In Windows 2000, there was typically one GC on every site in order to prevent user logon failures across the network.

27) What is GC? How many required for A Tree?

A) Global Catalog server is a Searchable Index book. With this we can find out any object in the Active Directory. Also it works as logon authentication for Group memberships. We can have each domain controller in domain or only first domain controller in a domain.

28) What is Global Catalog server?

A) Global Catalog Server maintains full information about its own domain and partial information about other domains. It is a forest wide role.

A global catalog server is a domain controller it is a master searchable database that contains information about every object in every domain in a forest. The global catalog contains a complete replica of all
objects in Active Directory for its host domain, and contains a partial replica of all objects in Active Directory for every other domain in the forest. It have two important functions:
i)Provides group membership information during logon and authentication
ii)Helps users locate resources in Active Directory

29) Can I change password if my machine’s connectivity to DC who holds PDC emulator role has been fails?

A)     No you cannot change the password.

30) How Can I Deploy the Latest Patched in Pc through G.P. without having the Admin Right in PC?

A) Create a batch file and place all the patches in the Netlogon, and deploy the batch file through GP to all the pc so the same should take affect after restarting the pc.

The above answer is incorrect.

You cannot deploy a batch file using group policy. You can only publish or assign .msi packages or Zap files. They are the only two valid file formats allowable when using “intellimirror” in active directory.

If you create a script and assign it to the STARTUP script in a GPO applied to the COMPUTER and not the USER, then it runs as a local administrator on the computer.

31) Difference between 2000 & 2003.

A)

1. We can’t rename domain in Win2k, u can rename in Win2k3

2. IIS 5.0 in Win2k and IIS 6.0 in Win2k3

3. No Volume Shadow Copying in Win2k, it’s available in Win2k3

4. Active Directory Federation Systems in Win2k3

Like that some other security features added in Win2k3, main features are above

32) What is hot fix?

A)     It is fix, which Microsoft release whenever there is a bug or for updation of Operating system.

33) What is paging?

A) If a program references a memory location within a virtual page that is not available, the hardware generates a page fault. When this occurs, the memory management hardware invokes an operating system routine that loads the required page from auxiliary storage (e.g., a paging file on disk) and turns on the flag that indicates the page is available. The hardware then adds the offset denoted by the low-order bits in the address register to the start location of the physical page, accesses the requested memory location, and returns control to the application that originally tried to access the memory. This process takes place transparently to the application addressing the memory. This scheme is called paging.

34) Explain hidden shares?

A) Hidden or administrative shares are share names with a dollar sign ($) appended to their names. Administrative shares are usually created automatically for the root of each drive letter. They do not display in the network browse list.

35) How do the permissions work in Windows 2000? What permissions does folder inherit from the parent?

A)     When you combine NTFS permissions based on users and their group memberships, the least restrictive permissions take precedence. However, explicit Deny entries always override Allow entries.

36) Why can’t I encrypt a compressed file on Windows 2000?

A) You can either compress it or encrypt it, but not both.

37) If I rename an account, what must I do to make sure the renamed account has the same permissions as the original one?

A) Nothing, it’s all maintained automatically.

38) What’s the most powerful group on a Windows system?

A) Administrators.

39) What are the accessibility features in Windows 2000?

A) StickyKeys, FilterKeys Narrator, Magnifier, and On-Screen Keyboard.

40) Why can’t I get to the Fax Service Management console?

A) You can only see it if a fax had been installed.

41) What do I need to ensure before deploying an application via a Group Policy?

A) Make sure it’s either an MSI file, or contains a ZAP file for Group Policy.

42) How do you configure mandatory profiles?

A) Rename ntuser.dat to ntuser.man

43) I can’t get multiple displays to work in Windows 2000.

A) Multiple displays have to use peripheral connection interface (PCI) or Accelerated Graphics Port (AGP) port devices to work properly with Windows 2000.

44) What’s a maximum number of processors Win2k supports?

A)  2

45) I had some NTFS volumes under my Windows NT installation. What happened to NTFS after Win 2k installation?

A) It got upgraded to NTFS 5.

46) How do you convert a drive from FAT/FAT32 to NTFS from the command line?

A) convert c: /fs:ntfs

47) Explain APIPA.

A) Auto Private IP Addressing (APIPA) takes effect on Windows 2000 Professional computers if no DHCP server can be contacted. APIPA assigns the computer an IP address within the range of 169.254.0.0 through 169.254.255.254 with a subnet mask of 255.255.0.0.

48) How does Internet Connection Sharing work on Windows 2000?

A)     Internet Connection Sharing (ICS) uses the DHCP Allocator service to assign dynamic IP addresses to clients on the LAN within the range of 192.168.0.2 through 192.168.0.254. In addition, the DNS Proxy service becomes enabled when you implement ICS.

49) I can’t seem to access the Internet, don’t have any access to the corporate network and on ipconfig my address is 169.254.*.*. What happened?

A) The 169.254.*.* netmask is assigned to Windows machines running 98/2000/XP if the DHCP server is not available. The name for the technology is APIPA (Automatic Private Internet Protocol Addressing).

50) We’ve installed a new Windows-based DHCP server, however, the users do not seem to be getting DHCP leases off of it.

A) The server must be authorized first with the Active Directory.

51) How can you force the client to give up the DHCP lease if you have access to the client PC?

A) ipconfig /release

52) What authentication options do Windows 2000 Servers have for remote clients?

A)     PAP, SPAP, CHAP, MS-CHAP and EAP.

53) What are the networking protocol options for the Windows clients if for some reason you do not want to use TCP/IP?

A)     NWLink (Novell), NetBEUI, AppleTalk (Apple).

54) What is data link layer in the OSI reference model responsible for?

A)     Data link layer is located above the physical layer, but below the network layer. Taking raw data bits and packaging them into frames. The network layer will be responsible for addressing the frames, while the physical layer is responsible for retrieving and sending raw data bits.

55) What is binding order?

A)     The order by which the network protocols are used for client-server communications. The most frequently used protocols should be at the top.

56) How do cryptography-based keys ensure the validity of data transferred across the network?

A) Each IP packet is assigned a checksum, so if the checksums do not match on both receiving and transmitting ends, the data was modified or corrupted.

57) Should we deploy IPSEC-based security or certificate-based security?

A) They are really two different technologies. IPSec secures the TCP/IP communication and protects the integrity of the packets. Certificate-based security ensures the validity of authenticated clients and servers.

58) What is LMHOSTS file?

A) it’s a file stored on a host machine that is used to resolve NetBIOS to specific IP addresses.

59) What’s the difference between forward lookup and reverse lookup in DNS?

A) Forward lookup is name-to-address; the reverse lookup is address-to-name.

60) How can you recover a file encrypted using EFS?

A) Use the domain recovery agent.

61) What is IPv6?

A) Internet Protocol version 6 (IPv6) is a network layer IP standard used by electronic devices to exchange data across a packet-switched internetwork. It follows IPv4 as the second version of the Internet Protocol to be formally adopted for general use. It is a 128 bit size address. Here we can see total 8 octets each octet size is 16 bits.

62) What is multimaster replication?

A)     In addition to storing primary zone information in DNS we can also store it in active directory as active directory object. This integrates DNS with active directory in order to take advantage of active directory features. The benefits are

  • Zone can be modified from any domain controller within the domain and this information is automatically updated or replicated to all the other domain controllers along with the active directory replication. This replication is said to be Multimaster replication.
  • We no longer face the standard DNS server drawbacks. In standard DNS server only the primary server can modify the zone and then replicate the changes to other domain controllers (It was in windows NT4 before). But when DNS gets integrated with AD .Zone can be modified and replicated from any domain controller.
  • Fault tolerance
  • Security: You can prevent access to any updates to zone or individual record preventing insecure dynamic updates.

63) What is RSoP?

A) Resultant Set of Policy (RSoP) is provided to make policy modification and trouble shooting easier. RSoP is the query object it has two modes:

1. Logging mode: Polls existing policies and the reports the result of the query.

2. Planning mode: The questions ask about the planned policy and the report the result of the query.

64) Difference between NTFS and FAT32

A)

NTFS

FAT32

Allows access   local to Win2k, Win2k3, WinXP, WinNT4 with SP4 & later may get access for   some file. Fat 32 Allows   access to Win95, Win98, WinMe, Win2k, WinXP on local partition.
Maximum size of   partition is 2 Terabytes & more. Maximum size of   partition is upto 2 TB.
Maximum File   size is upto 16TB. Maximum File   size is upto 4 GB.
File &   folder Encryption is possible File &   folder Encryption is not possible.
Support 255   characters long file name FAT support 8.3   character file name( avail. in FAT32)

65) What is Microsoft Software Assurance?

A) It means that if in future some upgrade version is introduced in market, then software assurance allows upgrading the license without paying any extra cost.

 66) How is user account security established in Windows Server 2003?

A) When an account is created, it is given a unique access number known as a security identifier (SID). Every group to which the user belongs has an associated SID. The user and related group SIDs together form the user account’s security token, which determines access levels to objects throughout the system and network. SIDs from the security token are mapped to the access control list (ACL) of any object the user attempts to access.

67) If I delete a user and then create a new account with the same username and password, would the SID and permissions stay the same?

A) No. If you delete a user account and attempt to recreate it with the same user name and password, the SID will be different.

68) What do you do with secure sign-ons in an organization with many roaming users?

A) Credential Management feature of Windows Server 2003 provides a consistent single sign-on experience for users. This can be useful for roaming users who move between computer systems. The Credential Management feature provides a secure store of user credentials that includes passwords and X.509 certificates.

69) Anything special you should do when adding a user that has a Mac?

A) “Save password as encrypted clear text” must be selected on User Properties Account Tab Options, since the Macs only store their passwords that way.

70)  What remote access options does Windows Server 2003 support?

A)  Dial-in, VPN, dial-in with callback.

71)  Where are the documents and settings for the roaming profile stored?

A)     All the documents and environmental settings for the roaming user are stored locally on the system, and, when the user logs off, all changes to the locally stored profile are copied to the shared server folder. Therefore, the first time a roaming user logs on to a new system the logon process may take some time, depending on how large his profile folder is.

72)  Where are the settings for all the users stored on a given machine?

A)     \Document and Settings\All Users

73)   What languages can you use for log-on scripts?

A)     JavaScipt, VBScript, DOS batch files (.com, .bat, or even .exe)

74)   How do you double-boot a Win 2003 server box?

A)     The Boot.ini file is set as read-only, system, and hidden to prevent unwanted editing. To change the Boot.ini timeout and default settings, use the System option in Control Panel from the Advanced tab and select Startup.

75)   What do you do if earlier application doesn’t run on Windows Server 2003?

A)     When an application that ran on an earlier legacy version of Windows cannot be loaded during the setup function or if it later malfunctions, you must run the compatibility mode function. This is accomplished by right-clicking the application or setup program and selecting Properties –> Compatibility –> selecting the previously supported operating system.

76)   If you uninstall Windows Server 2003, which operating systems can you revert to?

A)     Win ME, Win 98, 2000, XP. Note, however, that you cannot upgrade from ME and 98 to Windows Server 2003.

77)   How do you get to Internet Firewall settings?

A)     Start –> Control Panel –> Network and Internet Connections –> Network Connections.

78)   What’s new in Windows Server 2003 regarding the DNS management?

A)     When DC promotion occurs with an existing forest, the Active Directory Installation Wizard contacts an existing DC to update the directory and replicate from the DC the required portions of the directory. If the wizard fails to locate a DC, it performs debugging and reports what caused the failure and how to fix the problem. In order to be located on a network, every DC must register in DNS DC locator DNS records. The Active Directory Installation Wizard verifies a proper configuration of the DNS infrastructure. All DNS configuration debugging and reporting activity is done with the Active Directory Installation Wizard.

79)   When should you create a forest?

A)     Organizations that operate on radically different bases may require separate trees with distinct namespaces. Unique trade or brand names often give rise to separate DNS identities. Organizations merge or are acquired and naming continuity is desired. Organizations form partnerships and joint ventures. While access to common resources is desired, a separately defined tree can enforce more direct administrative and security restrictions.

80)   How can you authenticate between forests?

A)     Four types of authentication are used across forests: (1) Kerberos and NTLM network logon for remote access to a server in another forest; (2) Kerberos and NTLM interactive logon for physical logon outside the user’s home forest; (3) Kerberos delegation to N-tier application in another forest; and (4) user principal name (UPN) credentials.

81)   What’s the difference between local, global and universal groups?

A)     Domain local groups assign access permissions to global domain groups for local domain resources. Global groups provide access to resources in other trusted domains. Universal groups grant access to resources in all trusted domains.

82)   I am trying to create a new universal user group. Why can’t I?

A)     Universal groups are allowed only in native-mode Windows Server 2003 environments. Native mode requires that all domain controllers be promoted to Windows Server 2003 Active Directory.

83)   What is LSDOU?

A)     Its group policy inheritance model, where the policies are applied to Local machines, Sites, Domains and Organizational Units.

84)   Why doesn’t LSDOU work under Windows NT?

A)     If the NTConfig.pol file exist, it has the highest priority among the numerous policies.

85)   Where are group policies stored?

A)     %SystemRoot%System32\GroupPolicy

86)   What is GPT and GPC?

A)     Group policy template and group policy container.

87)   Where is GPT stored?

A)     %SystemRoot%\SYSVOL\sysvol\domainname\Policies\GUID

88)   You change the group policies, and now the computer and user settings are in conflict. Which one has the highest priority?

A)     The computer settings take priority.

89)   You want to set up remote installation procedure, but do not want the user to gain access over it. What do you do?

A)     gponame–> User Configuration–> Windows Settings–> Remote Installation Services–> Choice Options is your friend.

90)   What’s contained in administrative template conf.adm?

A)     Microsoft NetMeeting policies

91)   How can you restrict running certain applications on a machine?

A)     Via group policy, security settings for the group, then Software Restriction Policies.

92)   You need to automatically install an app, but MSI file is not available. What do you do?

A)     A .zap text file can be used to add applications using the Software Installer, rather than the Windows Installer.

93)   What’s the difference between Software Installer and Windows Installer?

A)     The former has fewer privileges and will probably require user intervention. Plus, it uses .zap files.

94)   What can be restricted on Windows Server 2003 that wasn’t there in previous products?

A)     Group Policy in Windows Server 2003 determines a users right to modify network and dial-up TCP/IP properties. Users may be selectively restricted from modifying their IP address and other network configuration parameters.

95)   How frequently is the client policy refreshed?

A)     90 minutes give or take.

96)   Where is secedit?

A)     It’s now gpupdate.

97) You want to create a new group policy but do not wish to inherit.

A)     Make sure you check Block inheritance among the options when creating the policy.

98)  What is “tattooing” the Registry?

A)     The user can view and modify user preferences that are not stored in maintained portions of the Registry. If the group policy is removed or changed, the user preference will persist in the Registry.

99)  How do you fight tattooing in NT/2000 installations?

A)     You can’t.

100)  How do you fight tattooing in 2003 installations?

A)     User Configuration – Administrative Templates – System – Group Policy – enable – Enforce Show Policies Only.

101)  What does IntelliMirror do?

A)     It helps to reconcile desktop settings, applications, and stored files for users, particularly those who move between workstations or those who must periodically work offline.

102)  What’s the major difference between FAT and NTFS on a local machine?

A)     FAT and FAT32 provide no security over locally logged-on users. Only native NTFS provides extensive permission control on both remote and local files.

103)   How do FAT and NTFS differ in approach to user shares?

A)     They don’t, both have support for sharing.

104)   Explan the List Folder Contents permission on the folder in NTFS.

A)     Same as Read & Execute, but not inherited by files within a folder. However, newly created subfolders will inherit this permission.

105)   I have a file to which the user has access, but he has no folder permission to read it. Can he access it?

A)     It is possible for a user to navigate to a file for which he does not have folder permission. This involves simply knowing the path of the file object. Even if the user can’t drill down the file/folder tree using My Computer, he can still gain access to the file using the Universal Naming Convention (UNC). The best way to start would be to type the full path of a file into Run… window.

106) For a user in several groups, are Allow permissions restrictive or permissive?

A)     Permissive, if at least one group has Allow permission for the file/folder, user will have the same permission.

107)   For a user in several groups, are Deny permissions restrictive or permissive?

A)     Restrictive, if at least one group has Deny permission for the file/folder, user will be denied access, regardless of other group permissions.

108) What hidden shares exist on Windows Server 2003 installation?

A)     Admin$, Drive$, IPC$, NETLOGON, print$ and SYSVOL.

109)   What’s the difference between standalone and fault-tolerant DFS (Distributed File System) installations?

A)     The standalone server stores the Dfs directory tree structure or topology locally. Thus, if a shared folder is inaccessible or if the Dfs root server is down, users are left with no link to the shared resources. A fault-tolerant root node stores the Dfs topology in the Active Directory, which is replicated to other domain controllers. Thus, redundant root nodes may include multiple connections to the same data residing in different shared folders.

110)   We’re using the DFS fault-tolerant installation, but cannot access it from a Win98 box.

A)     Use the UNC path, not client, only 2000 and 2003 clients can access Server 2003 fault-tolerant shares.

111)  Where exactly do fault-tolerant DFS shares store information in Active Directory?

A)     In Partition Knowledge Table, which is then replicated to other domain controllers.

112)   Can you use Start->Search with DFS shares?

A)     Yes.

113)  What problems can you have with DFS installed?

A)     Two users opening the redundant copies of the file at the same time, with no file-locking involved in DFS, changing the contents and then saving. Only one file will be propagated through DFS.

114)    I run Microsoft Cluster Server and cannot install fault-tolerant DFS.

A)     Yeah, you can’t. Install a standalone one.

115)   Is Kerberos encryption symmetric or asymmetric?

A)     Symmetric.

116)   How does Windows 2003 Server try to prevent a middle-man attack on encrypted line?

A)     Time stamp is attached to the initial client request, encrypted with the shared key.

117)   What hashing algorithms are used in Windows 2003 Server?

A)     RSA Data Security’s Message Digest 5 (MD5), produces a 128-bit hash, and the Secure Hash Algorithm 1 (SHA-1), produces a 160-bit hash.

118)   What third-party certificate exchange protocols are used by Windows 2003 Server?

A)     Windows Server 2003 uses the industry standard PKCS-10 certificate request and PKCS-7 certificate response to exchange CA certificates with third-party certificate authorities.

119)   What’s the number of permitted unsuccessful logons on Administrator account?

A)     Unlimited. Remember, though, that it’s the Administrator account, not any account that’s part of the Administrators group.

120)  If hashing is one-way function and Windows Server uses hashing for storing passwords, how is it possible to attack the password lists, specifically the ones using NTLMv1?

A)     A cracker would launch a dictionary attack by hashing every imaginable term used for password and then compare the hashes.

121)  What’s the difference between guest accounts in Server 2003 and other editions?

A)     More restrictive in Windows Server 2003.

122)   How many passwords by default are remembered when you check “Enforce Password History Remembered”?

A)     User’s last 6 passwords.

123)   What is presentation layer responsible for in the OSI model?

A)     The presentation layer establishes the data format prior to passing it along to the network application’s interface. TCP/IP networks perform this task at the application layer.

124)   Does Windows Server 2003 support IPv6?

A)     Yes, run ipv6.exe from command line to disable it.

125)   Can Windows Server 2003 function as a bridge?

A)     Yes, and it’s a new feature for the 2003 product. You can combine several networks and devices connected via several adapters by enabling IP routing.

126)   What’s the difference between the basic disk and dynamic disk?

A)     The basic type contains partitions, extended partitions, logical drivers, and an assortment of static volumes; the dynamic type does not use partitions but dynamically manages volumes and provides advanced storage options

127)   What’s a media pool?

A)     It is any compilation of disks or tapes with the same administrative properties.

128)   How do you install recovery console?

A)     C:\i386\win32 /cmdcons, assuming that your Win server installation is on drive C.

129)   What’s new in Terminal Services for Windows 2003 Server?

A)     Supports audio transmissions as well, although prepare for heavy network load.

130)   Describe the process of clustering with Windows 2003 Server when a new node is added.

A)     As a node goes online, it searches for other nodes to join by polling the designated internal network. In this way, all nodes are notified of the new node’s existence. If other nodes cannot be found on a preexisting cluster, the new node takes control of the quorum resources residing on the shared disk that contains state and configuration data.

131)  What applications are not capable of performing in Windows 2003 Server clusters?

A)     The ones written exclusively for NetBEUI and IPX.

132)  What’s a heartbeat?

A)     Communication processes between the nodes designed to ensure node’s health.

133)   What’s a threshold in clustered environment?

A)     The number of times a restart is attempted, when the node fails.

134)  You need to change and admin password on a clustered Windows box, but that requires rebooting the cluster, doesn’t it?

A)     No, it doesn’t. In 2003 environment you can do that via cluster.exe utility which does not require rebooting the entire cluster.

135)  Which add-on package for Windows 2003 Server would you use to monitor the installed software and license compliance?

A)     SMS (System Management Server).

136)  Which service do you use to set up various alerts?

A)     MOM (Microsoft Operations Manager).

Clustering

A new event log event has been created to address certain situations in which the Cluster service account becomes excessively restricted by domain policy. The new event ID is 1239. The event text includes troubleshooting information.

Data access components

XmlLite is new with Windows Server 2003 SP2. XmlLite is a fast, low-level, native XML parser with a small memory footprint.

Distributed systems

New options have been added to the Dcdiag.exe Domain Name System (DNS) tests to generate XML tags when the tests are run with the /test:dns option. It can be used to more easily parse the verbose log that the DNS tests generate.

File systems

Icacls.exe is an upgrade of the Cacls.exe tool in Windows Server 2003 SP2, and can be used to reset the access control lists (ACLs) on files from Recovery Console, and to back up ACLs. Also, unlike Cacls.exe, Icacles.exe correctly propagates the creation of inherited ACLs and changes to them.

Microsoft Message Queuing

The default storage limit for message queuing has been changed to 1 gigabyte (GB). If you choose to have a storage limit of more than 1 GB, you can change the storage limit setting in Microsoft Management Console (MMC) on the General tab of Message Queuing Properties.

Networking and communications

1. Includes an update that enables you to simplify the creation and maintenance of Internet Protocol security (IPsec) policy. This update enables you to use an IPsec “Simple Policy”. For most environments, the installation of this update allows you to reduce the number of IPsec filters that are required for a Server Isolation deployment or for a Domain Isolation deployment. You can reduce the number of IPsec filters from many hundreds of filters to only two filters.

3. Group Policy support for non-broadcasting networks and Wi-Fi Protected Access 2 (WPA2) settings has been added to the Windows wireless client in Windows Server 2003 SP2. This update allows the Windows wireless client to accept additional wireless Group Policy configuration options. These new settings include support for WPA2 parameters and non-broadcast networks.

4. The Windows wireless client now supports WPA2, which enables you to take advantage of high levels of standards-based connection and encryption security. New security features include:

Non-broadcast network profiles are now marked with a flag to improve the security of the Windows wireless client.

Windows will not automatically connect to a peer-to-peer network, even if it has been automatically saved in the preferred network list. You must manually connect to a peer-to-peer network profile.

Windows Deployment Services

Remote Installation Services is replaced by Windows Deployment Services. You can use Windows Deployment Services to set up new computers through a network-based installation without having to be physically present at each computer and without having to install directly from DVD media.
