Remove and Re-Join that machine to the domain server and run this command through command prompt on client machine "gpupdate /Force"

thanks for your suggention however it might cause some error.
That Machine is WSUS and Microsoft FCS server and i can see in MS SQL 2005 dB log section of WinNT which says the DC did not allow Macine (WSUS Server with its IP ) to claim by its name

i also found advapi is the source which is also creating some issue.

You need to scan the machine by some good anitivurs & make sure system is running with latest SP & patches which keeps virus/worm at bay.

As because the Solution resolved the issue and found what could be the other cause of WSUS.
