I also have Deep Freeze. I have a Ghosted image of our
computers on a Quantum Snap 80 gig drive. I turn off Deep
Freeze each Friday at 3:00 when our Lab closes or when
there are critical updates either from Norton or
Microsoft. I do not like leaving computers on unprotected
at night for the very reasons that you have stated. I
don't mind getting my hands dirty, but i guess you can
have Deep Freeze set to be off when you lab is closed
during the day, during the week when you are in and have
Norton and Microsoft push updates down to the computer....

If you need to call or e-mail me, don't hesitate.
