[Casper] Dual Boot - Time Sync Issues

[Bozorgzadeh, Amir J]

The fix is to go in on Windows side registry and Include this....

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
"RealTimeIsUniversal"=dword:00000001

This fixes the fact that Windows uses GMT and this makes it use UTC like the mac. You will not be able to log in using your AD account since it relies on your clock being in sync with AD server and it is way off. Took a while to find but there is info on it out there. I had same problem a while back but this fixed it when I did this to my Boot Camp image. That is why your mac side usually works fine with a local ID to log in. The clock will autofix itself once you log in if you have it syncing that way. Not so if using AD.

Hope it helps you out.

Just when I thought I finally had my Dual Boot deployment all dialed in.. I ran into one final hurdle!

Has anyone else had issues with the clock being out of sync when switching back and forth between Mac OS X and Windows Vista? (Both Operating systems bound to AD)

I do have the Mac side pointed towards our district time server, and Windows 'should' pull from our AD server. The problem on the Windows side is that since the system on boot is so far off on time, it never seems to sync with the AD server. (Also locks non-local users out since there is no sync with AD at that point).

I have run the AppleTime.exe as a startup service on the Windows side, and also checked any other Time Zone settings I can think of between both OS's and no luck.

I can go in and set both sides with the correct times and they will hold hold for awhile (roughly an hour or so). But in any case, after some amount of time the clocks get out of sync and then we have AD login issues on both OS's.

I know there are quite a few of you guys out there running dual-deployment, so have you run into this issue at all?

Thanks for any ideas!
