Preventing Multiple users from logging on to my personal workstation….

Hi Everyone!

…Ok here’s the problem Im a Win 2000 Pro network admin working on the 2nd shift support team… I have recently setup my own personal workstation OS Win 2000 pro in my own personal area. However when I arrive to my workstation on my shift I always seem to find someone sitting at my workstation…. Yes Im fed up with this smelly ass sitting at my workstation sorry but its the truth…. How can I prevent multiple users from logging on to my PC?

P.S I dont want to start setting restriction on user accounts. All I want to do is restrict multiple users from logging on to my PC.

Thanks for your help!
