[OPLINTECH] clever children...

... have found a way to circumvent our pc reservation time limit system. 
they log on as usual, then launch a program called process explorer to kill 
the pcreservation program.  this allows them to stay on for an unlimited 
amount of time.

I just discovered this today, and the things I have tried have not been 
foolproof in preventing them from launching the program.  We allow people to 
save to flash drives, and I don't want to restrict that.  However, using 
Windows 2003 server, and setting restrictions on launching programs from 
removable media doesn't prevent a user from launching process explorer from 
a flash drive.

Does anyone have any suggestions?  Is there something I have overlooked. 
(Parenthetically, this program seems like it would be a handy tool for 
techies looking for a quick way to close programs; much more elegant than 
task manager--and free, to boot.)

thanks for any help
