WORKAROUND
Try the following steps; Some of these steps might work. Rename/Delete “%Windir%\WindowsUpdate.log” before you start to see the latest detection.
1. If you have a proxy server –
Stop Automatic Update Service – “Net stop wuauserv“.
Run the following command: “proxycfg.exe -u”.
Start Automatic Update Service – “Net start wuauserv“.
Force update detection and see if that works.
2. Re-create the Datastore –
Stop Automatic Update Service – “Net stop wuauserv“.
Rename/delete “%Windir%\SoftwareDistribution” folder.
Start Automatic Update Service – “Net start wuauserv“.
Force update detection and see if that works.
3. Try to force install WUA.
Download WUA WindowsUpdateAgent20-x86.exe from http://go.microsoft.com/fwlink/?LinkId=43264.
and run the following command: “WindowsUpdateAgent20-x86.exe /wuforce“.
Post your results from “%Windir%\WindowsUpdate.log” on microsoft.public.windows.server.update_services.
NOTE:
You will loose reporting events when you rename or delete the Datastore folder (“%Windir%\SoftwareDistribution\ReportingEvents.log”).
Drop me a comment if these steps work.

Thanks !
After following the third step it worked. Thank you very much
And yet again, Microsoft releases another product that doesn’t always work out of the box. I had to use the 3rd solution to fix a new installation of Windows 2003 server to update from our WSUS server.
Thanks for this posting, it sure helped.
