Active Directory and Domain Interview Qestions- Part 2

1) What is difference between Server 2003 vs 2008?
1. Virtualization. (Windows Server 2008 introduces Hyper-V (V for Virtualization) but only on 64bit versions. More and more companies are seeing this as a way of reducing hardware costs by running several 'virtual' servers on one physical machine.)
2. Server Core (provides the minimum installation required to carry out a specific server role, such as for a DHCP, DNS or print server)
3. Better security.
4. Role-based installation.
5. Read Only Domain Controllers (RODC).
6. Enhanced terminal services.
7. PowerShell - Microsoft's command line shell and scripting language has proved popular with some server administrators.
8. IIS 7 .
9. Bitlocker - System drive encryption can be a sensible security measure for servers located in remote branch offices. >br> The main difference between 2003 and 2008 is Virtualization, management. 2008 has more in-build components and updated third party drivers.

2) What are the requirements for installing AD on a new server?
1. An NTFS partition with enough free space.
2. An Administrator's username and password.
3. The correct operating system version.
4. A NIC Properly configured TCP/IP (IP address, subnet mask and - optional - default gateway).
5. A network connection (to a hub or to another computer via a crossover cable) .
6. An operational DNS server (which can be installed on the DC itself) .
7. A Domain name that you want to use .
8. The Windows 2000 or Windows Server 2003 CD media (or at least the i386 folder) .

3) How can you forcibly remove AD from a server

    Demote the server using dcpromo /forceremoval, then remove the metadata from Active directory using ndtsutil.

    costs by running several 'virtual' servers on one physical machine.)

5) How do you view replication properties for AD partitions and DCs?

    By using replication monitor .Go to start > run > type replmon

6) What is KCC ?

1. Knowledge Consistency Checker (KCC)

2. When site and sitelinks are  configured kcc will automatically make connection between sites for.

3. If network goes down kcc will reconfigure the connection between the site to ensure active directory replication will happen.

4. kcc runs in the background doesnot need to be configured manually

7) What are the processes involved in the FRS?

    FRS is File replication service which is responsible for replicating Sysvol folder and the DFS

Information

8) Which protocol does FRS uses for directory replication?

    RPC over IP for inter-site and intra-site and uses port no 135.

9) What is the physical and logical structure of AD

 Active directory physical structure is a hierarchal structure which fallows  Forests—Trees—Domains—Child Domains—Grand Child—etc

Active directory is logically divided into 3 partitions

1.Configuration partition 2. Schema Partition 3. Domain partition 

10) What System State backup contains ?
     Contains Startup files,
     Registry
     Com + Registration Database
     Memory Page file
     System files
    AD information
    Cluster Service information
    SYSVOL Folder
