fix for Daylight saving time early start

[wpshooter]

At work here, all of our XP workstations had the M/S patch for fixing the computer for the 2007 early deployment of daylight saving time ran on them Friday, March 9th or earlier.

However when we got to work this moring the were only 2 workstations in the office (and the LAN server) that had the correct time displayed. ALL of the others were 1 hour behind inspite of having the patch run on them.

Are there any ideas as to either how or why this happened ?

Thanks.

wow super creepy. We both created the same post at the SAME TIME! Another sign of Y2chaos!

Potential workaround:

Set a different time zone, hit apply. Set correct time zone, hit apply. Should snap to correct time.

Thanks, understand how to fix.

Would like to know why patch worked it some cases but not in other ?

Thanks.

Normally I would suggest opening a case with MS but I'm quite sure they are already looking into it. If some sort of fix is needed I would expect it very quickly.

I would suggest starting here for now:

I'll spin up a thread with the same link and see if I can get it stickied for a few days.

I am wondering if it is possible that the reason that most of the computer were not updated properly was because some of the other available Microsoft security, etc. updates had not been applied to those workstations PRIOR to having the daylight savings time update applied to them.

The reason I am thinking this is because mine (which did change to the correct time on Saturday night) WAS up to date on all of the available M/S patches whereas I suspect that most of the others in the office were NOT.

Thanks.

Are the ones that didn't update running SP2? If they were running SP1 or earlier, the patch doesn't work, since they are not supported OSs

 

[wpshooter]

Yes, I am fairly confident that they are all on SP2.

But they have not had all of the recent security (and other) updates applied.

Thanks.

Living in Arizona has its advantages. No changes were necessary. Could you not set your time zone as Arizona then manually adjust the time any time you felt like it?

If this is an AD domain DON"T change the time manually.

Why not ?

Are you talking about servers or both servers and workstation ?

Thanks.

All of them. AD uses UTC for Kerberos authentication, so if you change the time manually, time will be out of the default 5 minute tolerance.

If you changed ALL of the machines to the same time, it would probably work, but it still not recommended. You would more likely wind up in a situation where some machines have the DST patch while other don't. In that case, even if two machines appear to have the same time, they could still have different UTC times.

If you screw up the time in AD, nothing will work. Clients won't be able to logon, directory replication will break, etc.
