client not communicating with WSUS server

my client PC is the only PC on our network that is not communicating with our
WSUS server. nothing has changed from what i remember, but the last time it
talked with WSUS was 9/13/06. my connection to the network is still good so
i'm not quite sure why this is happening. i have done much troubleshooting
including some registry fixes i've seen out there with no luck. i downloaded
the ClientDiag.exe file and it comes up showing everything passes, but at the
end it says:

VerifyWUServerURL() failed with hr=0x80072efd
A connection with the server could not be established

all other PCs on our network communicate with the WSUS server fine...any
ideas why one client is having issues?

 

The Microsoft Windows Server Update Services (WSUS) SelfUpdate service does not send
automatic updates
http://support.microsoft.com/kb/920659/en-us
When you try to use the Microsoft Windows Server Update Services (WSUS) SelfUpdate
service to send automatic updates to client computers, the client computers do not
receive the updates. Additionally, the client computers do not report to the WSUS
server.
When this occurs, the WSUS Administration console logs the following error message:
Check your server configuration. One or more Update Service components could not be
contacted. Check your server status and ensure that the Windows Server Update Service
is running.
Non-running services: SelfUpdate
The event log may also log the following event:
EVENT ID 506
Source: Windows Server Update
Description: The SelfUpdate Tree is not working. Clients may not be able to update to
the latest WUA client software and communicate with the WSUS Server.

Or perhaps try the WSUS Newsgroup
