Windows Activation error: Code 0x8007232b

Windows Activation error: Code 0x8007232b

I was trying to activate Windows Server 2008 and got this error:
“Activation Error: Code 0x8007232b .DNS Name does not exist”
Actually Windows was looking for KMS server for the activation . and when it did not find that , it threw error 0x8007232b.

Microsoft has a KB article for resolving the issue: http://support.microsoft.com/kb/929826
I used following method to resolve the issueThe solution worked for me was:

1. Cick All Programs, click Accessories, and then right-click Command Prompt.
2. Click Run as administrator.
3. At the command prompt, type the following command, and then press ENTER:
            slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
Note: In this command, the xxxxx-xxxxx-xxxxx-xxxxx-xxxxx placeholder represents your MAK product key.
4. Now try to activate the Windows online, you will succeed.
