Time Issues (Part Two)
So, upon rebooting several of the machines, I realized that the group policy did indeed get applied on the successful restart.

Question to Microsoft: Why doesn’t the “gpupdate” command update ALL of the group policy settings? This may be a silly (and old) question to some, but I think that if you make a group policy update tool, it should update the group policy, all of it.
What I learned is that group policy relating to user settings apparantly updates after logon and group policy relating to computer settings apparantly updates before logon (and isn’t affected by gpupdate). I could be wrong, but that’s what looks like is playing out on these machines.
Hmmmm… a little rant for today, but I’m glad that it works. Now my network time is now synced via NTP (SNTP actually), and the users can’t change it.
