Even though I am new to Server, I have successfully installed ArcGIS for Server 10.1, register folders, and publish a simple service.  Then I installed the ArcGIS Server Silverlight viewer.
Now I can no longer publish services or view services including the default World Cities service.  The computer just hangs when I try to publish.  I cannot get the Silverlight app to create a web map.
I have restarted the server but this has not helped.  The IS department assures me that we meet the specifications for the software.

Any advice is appreciated.
