Windows 2008 Migration

Hello, JJ KR!

The name remaining the same is normal.

This TechNet article tells how to change the name of a DC in a domain where it is the only DC.

From the article:

1. Open a Command Prompt as an administrator: On the Start menu, right-click Command Prompt, and then click Run as administrator. If the User Account Control dialog box appears, provide Domain Admins credentials, if required, and then click Continue.
2. At the command prompt, type the following command to add the new domain controller name, and then press ENTER:
netdom computername <CurrentComputerName> /add:<NewComputerName>
3.Type the following command to designate the new name as the primary computer name, and then press ENTER:
netdom computername <CurrentComputerName> /makeprimary:<NewComputerName>
4.Restart the computer.
5.After the computer restarts, open a Command Prompt.
6.At the command prompt, type the following command to remove the old domain controller name, and then press ENTER:
netdom computername <NewComputerName> /remove:<OldComputerName>



Cheers!
Sean

The reason is that when you did your base install you didn't change the name while it was still in the workgroup.

You should be ok changing it now.  As the warning says it might be unavailable for a period of time.

I would schedule this for after hours.

You generally don't want to rename DCs.  It can cause some weird behavior but everything should work itself out once the new name is fully integrated.

Dear Sean,

Thanks for replaying . I did as per your instruction. How ever the first command executed but second command its giving error.

C:\Users\Administrator>netdom computername W-IN-DC2K8 /add:W-IN-DC2012
The specified alternate computer name "W-IN-DC2012" does not contain a dot.
Although it is a valid DNS name, usually a DNS name consists of multiple
labels, for example server1.microsoft.com. This field MUST contain the full
DNS name of a computer.

Do you want to proceed (Y or N)?
Y

Is your 2008 domain controller still operational?  If so, just try the normal rename by clicking on "Change Settings".
