1.What’s the difference between local, global and universal groups? 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. 2.I am trying to create a new universal user group. Why can’t I? 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. 3.What is LSDOU? It’s group policy inheritance model, where the policies are applied to Local machines, Sites, Domains and Organizational Units. Why doesn’t LSDOU work under Windows NT? If the NTConfig.pol file exist, it has the highest priority among the numerous policies. 4.Where are group policies stored? %SystemRoot%System32\GroupPolicy 5.What is GPT and GPC? Group policy template and group policy container. 6.Where is GPT stored? %SystemRoot%\SYSVOL\sysvol\domainname\Policies\GUID 7.You change the group policies, and now the computer and user settings are in conflict. Which one has the highest priority? The computer settings take priority. 8.You want to set up remote installation procedure, but do not want the user to gain access over it. What do you do? gponame–> User Configuration–> Windows Settings–> Remote Installation Services–> Choice Options is your friend. 9.What’s contained in administrative template conf.adm? Microsoft NetMeeting policies 10.How can you restrict running certain applications on a machine? Via group policy, security settings for the group, then Software Restriction Policies. 11.You need to automatically install an app, but MSI file is not available. What do you do? A .zap text file can be used to add applications using the Software Installer, rather than the Windows Installer. 12.What’s the difference between Software Installer and Windows Installer? The former has fewer privileges and will probably require user intervention. Plus, it uses .zap files. 13.What can be restricted on Windows Server 2003 that wasn’t there in previous products? 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. 14.How frequently is the client policy refreshed? 90 minutes give or take. 15.Where is secedit? It’s now gpupdate. 16.You want to create a new group policy but do not wish to inherit. Make sure you check Block inheritance among the options when creating the policy. 17.What is "tattooing" the Registry? 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. 18.How do you fight tattooing in NT/2000 installations? You can’t. 19.How do you fight tattooing in 2003 installations? User Configuration - Administrative Templates - System - Group Policy - enable - Enforce Show Policies Only. 20.What does IntelliMirror do? 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. 21.What’s the major difference between FAT and NTFS on a local machine? FAT and FAT32 provide no security over locally logged-on users. Only native NTFS provides extensive permission control on both remote and local files. 23.How do FAT and NTFS differ in approach to user shares? They don’t, both have support for sharing. 24.Explan the List Folder Contents permission on the folder in NTFS. Same as Read & Execute, but not inherited by files within a folder. However, newly created subfolders will inherit this permission. 25.I have a file to which the user has access, but he has no folder permission to read it. Can he access it? 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. 26.For a user in several groups, are Allow permissions restrictive or permissive? Permissive, if at least one group has Allow permission for the file/folder, user will have the same permission. 27.For a user in several groups, are Deny permissions restrictive or permissive? Restrictive, if at least one group has Deny permission for the file/folder, user will be denied access, regardless of other group permissions. 28.What hidden shares exist on Windows Server 2003 installation? Admin$, Drive$, IPC$, NETLOGON, print$ and SYSVOL. 29.What’s the difference between standalone and fault- tolerant DFS (Distributed File System) installations? 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. 30.We’re using the DFS fault-tolerant installation, but cannot access it from a Win98 box. Use the UNC path, not client, only 2000 and 2003 clients can access Server 2003 fault-tolerant shares. 31.Where exactly do fault-tolerant DFS shares store information in Active Directory? In Partition Knowledge Table, which is then replicated to other domain controllers. 32.Can you use Start->Search with DFS shares? Yes. 33.What problems can you have with DFS installed? 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. 34.I run Microsoft Cluster Server and cannot install fault- tolerant DFS. Yeah, you can’t. Install a standalone one. 35.Is Kerberos encryption symmetric or asymmetric? Symmetric. 36.How does Windows 2003 Server try to prevent a middle-man attack on encrypted line? Time stamp is attached to the initial client request, encrypted with the shared key. 37.What hashing algorithms are used in Windows 2003 Server? 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. 38.What third-party certificate exchange protocols are used by Windows 2003 Server? 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. 39.What’s the number of permitted unsuccessful logons on Administrator account? Unlimited. Remember, though, that it’s the Administrator account, not any account that’s part of the Administrators group. 40.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 cracker would launch a dictionary attack by hashing every imaginable term used for password and then compare the hashes. 41.What’s the difference between guest accounts in Server 2003 and other editions? More restrictive in Windows Server 2003. 42.How many passwords by default are remembered when you check "Enforce Password History Remembered"? User’s last 6 passwords. 1. How would you troubleshoot AD Replication ( Intersite & Intrasite ) and what are the tools which you would use - Event Viewer / RPC / Repadmin / DcDiag / Replmon / Subnet Information – Event ID 1311 / 1290 / 1586. Senario - There are 4 Sites – Site A – Site B – Site C – Site D. Site A connected to Site B, Site B connected to Site C, Site C connected to Site D, but Site D is not connected to Site A. So how long would replication take from Site A to Site D. Answer – Site to Site replication takes 15 min in Windows 2003 Domain, so it would take 45 min for an object to be replicated from Site A to Site D. 2. What are the various Attributes for an Object – Answer – Address, E-Mail, 3. Which are the different Naming Context in AD – Answer – Domain / Configuration / Schema / Application / Domain DNS / Forest DNS 4. How would you Force Replication in AD & FRS – Answer – AD Replication can be forced using Replmon, FRS Replication can be forced by a relevant D2 or D4. 5. Senario Based – A User in Site A changes his Password and then tries to Login in Site B, so would he be able to login with his new Password or would require to Login with Cached Credentials. Answer – Yes, the User would be able to Login to Site B with the new password as password replications are Urgent Replications and are triggered in 15 Sec. 6. What is FRS ? Why is it Used and what are the tools to monitor FRS ? Answer – FRS is used to replicate GPO’s and Scripts b/w DC’s and also used to Replicate DFS Data. Tools to monitor FRS are – FRSDiag / Ultrasound / Sonar / Event Viewer. 7. What are Morphed Folders and what are they created and what is the way to Troubleshoot them. Answer – Morphed folders are duplicate folders with same name created due to Replication Link Failure or Forced Traffic in DFS & FRS. 8. What is Sharing Voilation ? Answer – Sharing Voilation is multiple user accessing the same file while that file is Replicating through FRS or DFS and fails replication cause User are using the File and it is in use. Sharing Voilation can be troubleshot by doing a D2 on the Server. 9. What is Backlog Issue in FRS ? Answer – Backlog issue is when Server A is replicating files to Server B and Server B is not accepting those files then the files are accumulating and creating a Backlog on Server B. Troubleshooting step is D2 on Server B. 10. How would you flush and register a DNS Record – Answer – Ipconfig /flushdns & ipconfig /registerdns. 11. What are the Various Records for a DC in DNS ? Answer – Host A / GUID / Kerberos / GC Record / _MSDCS Record. 12. What is the difference b/w Primary Zone / AD Integrated Zone and Secondary Zone in terms of Usage and Replication. Answer – Primary Zone is a editable copy but replicated through DNS Replication. AD integrated zone is AD integrated and is replicated through AD. Secondary zone is a readonly copy of either Primary or AD Integrated Zone. 13. How would you troubleshoot disappeared DNS Records and what is the use of C Name Record ? 14. What is Scavenging and what are Stale Records in DNS ? Answer – Scavenging is automatic removal of Stale Records in DNS, default period is 7 days. 15. What are the tools to monitor GPO Replication – Answer – GPResult / Userenv / RSOP / GpoTool. 16. There are 1000 Users in an OU and you would like to apply a Policy to only 200 Users in that OU. How is that possible ? Answer – GPO Filtering. User and Computer part of a Policy can also be filtered if required. There is only 1 Password Policy per Domain no matter what. 17. How would you recover a deleted User / GPO or OU Answer – Study the KB 840001 and NTDSUtil Tool. 18. What are FSMO Roles – Answer – Study all the roles properly cause he might ask you to describe any one.
