Hi,
My PDC Emulator (windows server 2003) is in California (subnet a). I have another DC (GC only) in Texas (different time zone). I'm having problems getting the time syncronized on the Texas subnet b.
Any suggestions handling Net Time between different time zones?
Thanks,
muffin

Thanks for the input however, I'm a little hesitant to add that patch because it only speaks to Daylight Saving Time only and my concern is more so with how you handle Net Time when your PDC Emulator is in one time zone and you have machines in another that can't find a time source in the domain.

You are probably seeing w32time errors in your system logs, not only on the servers but also the workstations correct?

Event ID 29 - The time provider NtpClient is configured to acquire time from one or more time sources, however none of the sources are currently accessible ...

Thanks for your response. On my Win7 machine I'm getting Event ID 129 then a couple hours later Event ID 35. So, it can't find the time server then it does a while later, which is my PDC Emulator.

Let's try some basic analytics - from a command prompt of the domain controller, type:

     w32tm /monitor

This will check the time of the system against all other domain controllers in the domain.
Now run the same command on the Windows 7 computer.  You should have similar results.

Now try the following command from the Windows 7 computer:

     w32tm /resync

What are your results?

Check in your Domain level group policies for incorrect entries:
Computer Configuration > Administrative Templates > System > Windows Time Service > Time Providers

Thanks everyone for your input, I can't believe that I didn't catch this, but the subnet was not correct, nor was the Time Zone right which caused many problems. Once it was corrected, everything started working as expected.
