Last night after a reboot of the server (added RAM to server) my Exchange 2010 EMC gets stuck when attempting to connect or search for the "on-premises exchange server". The server the EMC is on IS the exchange server. It originally tries to connect to the Exchange server (Servername.contoso.com) which is the exchange server and is the same server the EMC is on. But after that it just moves to the "Searching for on-premises exchange server" and nothing happens. I have restarted all the Exchange services and even rebooted the server again.
