We have a mixture of 2k and xp PCs here and have recently implemented a new security policy where the screensaver is supposed to lock the workstation after 20 minuets. On all new PCs we simply set that setting for the "default user" and it has worked fine. However, now when we visit less than new PCs we have to make the change with the user logged in. So is there a way (reg setting?) that we can hit that will set this for all of the users that use the PC?
