time enabled password only access?

im looking for a program that say between the hours of 7am and 5pm you need to enter a password to beable to use either of my two computers that are on 24/7 folding?
but I don't want it to decrease my production #'s, that means no gay screensavers... just something to keep sombody from going online really

I'm not sure if it's possible, but you might be able to set up a scheduled task to run the Black Screen screensaver (command would be "c:\windows\system32\dllcache\scrnsave.scr /s" on my XP box) at the times you want. Then, click the "On Resume, Password Protect" checkbox in the Screensaver Properties.

I've never actually done this, so I don't know if the system will prompt for the password like it should, but if it does, it's probably the easiest solution that won't eat up CPU time .


EDIT: Just got home to test this, and it dosen't work... Bummer...
