Frequently Asked in Technical Round Question & Answer

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

The server must be authorized first with the Active Directory.

2.   How do you double-boot a Win 2003 server box?
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.

3.   What do you do if earlier application doesn’t run on Windows Server 2003?
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.

4.   What do you understand by Global Catalog and Global Catalog Server?
The global catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multidomain Active Directory forest. It provides the ability to locate objects from any domain without having to know the domain name.

5.   What is GCS ?
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 is responsible for providing group membership information during logon and authentication and helps users in locating resources in Active Directory.

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

7.   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.

8.   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.

9.   What is LSDOU?
It’s group policy inheritance model, where the policies are applied to Local machines, Sites, Domains and Organizational Units.

10.How can you restrict running certain applications on a machine?
We can do this 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?
.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 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.

14.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.

15.How do FAT and NTFS differ in approach to user shares?
They don’t, both have support for sharing.

16.Can you use Start->Search with DFS shares?

17.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.

18.I run Microsoft Cluster Server and cannot install fault-tolerant DFS.
Yeah, you can’t. Install a standalone one.

19.Is Kerberos encryption symmetric or asymmetric?

20.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.

21.Can Windows Server 2003 function as a bridge?
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.

22.Does Windows Server 2003 support IPv6?
Yes, run ipv6.exe from command line to disable it.

23.What’s the role of http.sys in IIS?
It is the point of contact for all incoming HTTP requests. It listens for requests and queues them until they are all processed, no more queues are available, or the Web server is shut down.,

24.Where’s ASP cache located on IIS 6.0? 
On disk, as opposed to memory, as it used to be in IIS 5.
