I have about 25 servers in my domain, 18 in Melbourne and 7 in Brisbane. Last weekend we changed over to daylight saving in Melbourne. All users in Brisbane have the correct time on their workstations (Brisbane does not have daylight saving) but their are about 20 users in Melbourne who still have the old time on their PC's. If I change the time on one of these PC's it reverts back to the wrong time in about 15 or 20 minutes. I installed the daylight saving patches on all servers and all servers are showing the correct time. All users have the correct time zone selected and daylight saving is ticked as it is on all the servers. Can anyone possibly tell me where the old pre-daylight saving time is coming from...I'm baffled!
