We have a new server running Windows 2012 Server Essentials. On one of the workstations, running Windows 8.1, we ran the connector software and received the message that the computer was successfully connected to the server. However under computer properties it still says that it's a member of WORKGROUP. And we never received the message that the stand-alone profile was being migrated. I uninstalled the connector and reinstalled it and got the same result.
