we are using a sonicwall 4200 to allow an external guest user to connect via rdp to one of our applications. all works fine until the user is finished and wants to exit the system. after using the applications "Exit" button to close all application windows, the remote windows (gray screen) dialog area remains open. "x" out warns of disconnecting, this is what users will end up doing. I have the ussers a/d "sessions" set to end a disconnected session in 1 minute but this does not happen. I checked and ts is configured for users config.
any suggestions welcome.
