title: Team Foundation Server Administration Console throws error message "Servicing"; tfsjobagent.exe has an error during job execution
body: <p>Randomly, the TFS 2010 Server stopped working.  When I go to the console to see what is going on, I get a simple &quot;Servicing&quot; error message.  When I click okay, none of the Team Project Collections actually show up.</p>
  <p>When I go to the Event Viewer and look at the log, I see the following message:</p>
  <blockquote>

  <p>I've done some googling and some people have suggested this is a sql server login issue.  There have been NO CONFIGURATION CHANGES of any kind to the database or the TFS application layer.</p>
