I have recently build ten (10) Intel iMac, and have noticed that on a Monday most machines will be at least 5 minutes to fast. Becasue these machine are on a Windows Domain, user's are unable to login, I have to login as Administrator and change the time. If the iMacs are left on the time is insync with the Server. All our older G5 don't have this problem. Is there a way to fix this? Thanks to everyone in aadvance.
