I have a need to be able to keep a windows 2000 workstation locked but still be able to VNC to it so I can remote control it. If I lock it, VNC can't connect and I don't see any options to send a ctrl+alt+del and the password.

I'm open to suggestions as long as they don't involve spending money (boss doesn't care if we have this tool or not and will not spend $$).

Any suggestions??
