We do some computationally intensive work and have a set of spare computers users can use for this purpose so their own computer is not bogged down. The users use remote desktop to log into the spare computers remotely to run these jobs. When 1 user is logged into a machine and a 2nd logs in with the same userid, the 1st user is bumped off without the 2nd user even aware this has happened. Is there a way to configure the client or the server so that the 2nd user is warned and has the option of aborting the log in before bumping off the 1st user?
Alternatively, is there a cheap or free alternative to remote desktop which provides similar functionality, but adds this level of coordination?
