Unfortunately the basic configuration only allows for three connections at any one time. Also, if someone just closes the client, their connection is not cleared. It will hang around in a disconnected state until someone connects to the physical machine to clear any unused connections.
There are two DOS commands which solve this problem. The oddly named;
qwinsta /server:SuperServerThe displayed list will include the session Id which you can use with the next command, rwinsta, to reset the sessions. Type the following to reset session 1 on SuperServer:
rwinsta 1 /server:SuperServerBe sure to pick sessions with the state “Disc” as connections marked as “Active” my really be active.
Often the simplest tools yield the biggest gains. The discovery of these two commands has saved many hours of work. I no longer have to go through the IT support process and have an engineer go to the physical machine.
