title: SQL Physical Connection is not usable
body: <p>My application moved to a new DEV SQL Server and I'm trying to update my EF model.  The database through Management Studio 2014 is able to connect (though truthfully, the connection has had some interruptions today).  However, i'm trying to update my EF model by adding 2 tables to it through the "Update Model From Database" (so obviously not using code first here).  I get the error:</p>
  
  <blockquote>
    <p>SQLException: A transport-level error has occurred when receiving
    results from the server. (provider: Session Provider, error: 19 -
    Physical connection is not usable).</p>
  </blockquote>
  
  <p>Sometimes, it errors on the first screen (Reading database information, please wait..., and times out).  Sometimes, I can get through the entire Update Wizard and click Finish, only to encounter the problem then.  Most errors related to this have occurred at runtime; I haven't found anything explicitly for fixing this problem at design-time...  Any ideas?  Maybe I need a permission on the database?</p>
