This is was the first thing I tried after reading this thread with no joy.
I'm running Server 2008 R1, and this IS NOT our Sharepoint server. It is, however, our WSUS server.
I will give this a shot and see if I can find the exact one. If I can find it should I go through the process of Stopping WDS service, killing the process, and restarting the WDS service?
That sounds about right, I will post with an update soon.
