Remote Desktop Log Files

I have remote users that use Winxp Pro Remote Desktop to access pc at work.
The uses will leave their pc and applications running so they can pickup were
they have left off when they exit the Remote Desktop connection. Then the use
reattaches to the desktop, the login script does not run because they use has
not logged off. I have the login script record use log in, logoff what pc
they logged into and what time.

Is there a way to record in the event log or create a log to see when a pc
is accessed remotely by Remote Desktop?


Thanks
John
