RDP Terminal Session and XP

XP supports only one RDP/Terminal Service session on the target machine and logs off other users. Starting a remote logon session from a second machine logs off the first remote logon session. The VSA uses the port relay to get through firewalls and gateways. To Windows XP, it appears as if the Terminal Server session is connecting from the localhost.

Warning: Using the credential of a currently logged on user confuses XP. It can not determine if the user is reactivating the existing session locally or remotely initiating a new connection. As a result Window XP may hang, requiring a reboot to recover. The VSA can not protect you from this. Do not log on using the user name of an already logged on account. See Remote Control > Control Machine for other types of remote control malfunctions.
