"The security database on the server does not have a computer account for this workstation trust relationship" error on DC

I I have a domain controller, which is running on Windows Server 2008 R2 Enterprise edition and an ADC running on Windows Server 2003 SMB.

Since Yesterday, I am facing a problem. I am unable to log in on my DC while I am able to log in on ADC.

When I am trying to log in on DC with Administrator account it is showing the error "The security database on the server does not have a computer account for this workstation trust relationship."

I have searched online tech forum and blogs but no luck.

I need someone help to recover my DC.

Thanks in Advance
