Disable multiple RDP sessions in windows server

RDP allows only one connection per account: each user has ONE desktop, and it can't be shared among multiple connections.

If he needs to launch several applications, you should delete the "launch application" from the shortcut's properties: that will allow him to see the desktop. There he can launch multiple applications as if he's using his desktop computer.

Cheers!

poor solution: make a login script. If the connection is not console, logoff:

logoff 1

This will logoff session 1. If you are connecting in rdp through the console, you are session 0 and not 1

you can detect better using qwinsta and a script to check output of it.
