As far as I know there is no way to intercept a CTRL-ALT-DELETE combination on a Windows NT/2k box. Nor the password box that pops up afterwards. I could be wrong though...
demerphq That is correct you can not intercept CTRL-ALT-DEL on NT based systems(NT/2000). That is a security feature (what? M$ security feature that works). That way when you log in with C-A-D there is no possibilty that a trojan could pop up a window instead.
