Win 2000 auto log off

I have W2K workstations logging onto a W2K domain. I need to know if there is a way on individual workstations to setup a policy to log off users automatically after a certian period of time. I don’t want this to be done through their domain ID. I want this to be done through the local policy. It also needs to be able to do a force close of all programs running. If this is not possible with native W2K, then please recommend a software that does do this.

Thanks in advance,
Bra-k
