------
The administrator of the server that is running Terminal Services may have set a timeout value on idle sessions. User may have been logged on to the computer previously, and then let the session go past the idle timeout limit, at which time User received the following warning two minutes prior to disconnection: Remote Desktop Disconnected
The remote session was ended because the idle timeout limit was reached. This limit is set my the server administrator or by network policies. When user reconnect, user is in the same session and the warning that user received for disconnection is still present in the session.

It is nothing to do with Cisco CAD
