I have two of my domain controllers which will not allow me to connect via the terminal services client. I get a message saying "The terminal server has ended the connection" via Windows and a "Connection reset by peer" message via RDP on Linux.
All DC's are in Remote Administration mode. Browsing the system logs I see an Event ID generated from TermServices that states: "Attempt to send a message to a disconnected communication port." Event ID 55. I can connect to both servers via Terminal Services Manager and they don't show and open sessions. I've reset the sessions anyway. I've ran a port scan against both machines and they show 3389 as open and listening, the service is also running.
