Terminating Active User Connections?

Question – Need help finding a way to terminate an active user connection in AD.

Background – We are downsizing and as people are leaving some are not wanting to go quietly (Sending out stupid email, messing w/ files…etc.) Most of the ones leaving are in satalite offices with no IT staff. I can change someones password and disable there account, but if they are still logged in they keep access until they log out. I need a way to boot their connection from the network to enforce the password change/disable.

We are running 2000 in native mode w/ AD and Exchange 2000.

Any suggestions would be greatly appriciated.

Thank you,

Mark
