I would like to make my workstation as secure as possible
by having it enter lock-mode after a fixed amount of
time. So after 30 minutes of inactivity the PC would go
into "lock mode" forcing the user to press ctrl-alt-delte
and to authenticate. I am working in a win200 and NT
environment. Any idea's would be helpful.
