WSUS Synchronization Failure

I am receiving an error on one of our WSUS downstream servers "Windows Server 2008 R2 Foundation," but all other WSUS downstream servers are not having this issue.
When I do a manual synchronization of WSUS from our clients server to our main WSUS server I receive the following error:
Synchronization Error Detail
An error occurred with the server's data store
SqlException: Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.
at Microsoft.UpdateServices.DatabaseAccess.DBConnection.DrainObsoleteConnections(SqlException e)
   at Microsoft.UpdateServices.DatabaseAccess.DBConnection.ExecuteReader()
   at Microsoft.UpdateServices.Internal.DataAccess.HideUpdatesForReplicaSync(String xmlUpdateIds)
   at Microsoft.UpdateServices.ServerSync.CatalogSyncAgentCore.ProcessHiddenUpdates(Guid[] hiddenUpdates)
   at Microsoft.UpdateServices.ServerSync.CatalogSyncAgentCore.ReplicaSync()
   at Microsoft.UpdateServices.ServerSync.CatalogSyncAgentCore.ExecuteSyncProtocol(Boolean allowRedirect)

Also, I receive an event log error 10022 for Windows Server Update Services saying:
The last catalog synchronization attemp was unsuccessful.

Finally, when going into WSUS and bringing up reports on specific pc's WSUS will crash or stay stuck on generating report.  

Any help will be thankful.

Have you run WSUS Cleanup Wizard on that server?
ByteCafeSupportAuthor Commented:
I have run the WSUS cleanup wizard on the server and tried another manual sync, but still having the issue of WSUS timing out at 98%.  
I try to click on the result details, but the report will not come up giving me any additional information.
When I go into the event viewer I still see an event id 10022 and 13002.

Anyone have any other suggestions to this issue?
What version of WSUS do you have on that server?  If it isn't the latest i would upgrade to that. (SP2 (3.2.7600.226)

The event ID 13002 indicates updates are failing because the files associated with those updates were deleted from the WSUS server.
do you also get an "HTTP status 404: The requested URL does not exist on the server"?

If so, run wsusutil reset to re-download the missing content, and then review the procedures you're using to manage the filesystem on your WSUS server.

Good hunting
