How do you connect to the control server?
On the server (running Windows Server 2008 R2 or Windows with RSAT), open Server Manager
Right-click Server Manager and select Connect to Another Computer
In the Connect to Another Computer window, type the name or browse to the server you want to connect to.
If you want to keep the remote connection and do not want to reconfigure the admin server name after each time, you can open a new MMC window, add the Server Manager snap-in, connect to the administrative server and save Repeat this snap-in.
