We have server 2003 - 32 bit, and have added some Win 7/64 bit machines to the domain. For a while, everything was great. Recently though, the Win 7 machines do not keep the same time as the domain, they all go 10-15 minutes fast. When we run the w32 commands, it shows that it is getting the time from the domain, but it does not last. Port 123 is open on the firewall, our remaining XP Pro machines work just fine, never more than 1 minute off a month. Can someone give me a clue as to what is going on so I can get this fixed?
