title: Getting "Unable to open the guest session" error
body: <p>I have a desktop application with DBMS sql server 2008 configured in a network.
  I can access to the database through SQL Server Management Studio from the computer in the network. But the application does not work on the same computer. Modifying the configuration file didn't help either. I'm always getting the error &quot;Unable to open the guest session.&quot;.</p>
  <p>Note: I'm on a Windows 7 machine.</p>
