I've got a couple NT guests that are behind an hour since daylight savings. They are using the time sync settings and are keeping good time aside from the hour. If I manually adjust the time, and press OK, the guests immediately revert back an hour. Doesn't make any difference if I uncheck the box to adjust automatically for day light savings.

Interestingly, if I type 'net time' on the guest, they say they are pulling their time from the correct server, but it is behind an hour. The server it is pulling the time from is correct, as is the host machine.

Any ideas how to fix this?

I know this is just a wild guess, but to test it, I would change the server time back an hour and see how the NT guest responds. That would test whether the guests are really pulling from the server or not.

daylight saving time? Set it manually.

Hmm, I can try that after hours and see what happens. I did try changing the time zone to Arizona time on the NT boxes and that has worked so far. When I run net time, now it shows the correct time. I wonder if there is a Year 2K issue in there somewhere.

IIRC there was a bug in the TZ code back then that a patch was used to fix this but those patches are long since gone. I think this might get it to work for you but test on a non production machine first. http://www.uic.edu/depts/accc/systems/d ... ndows.html Read the section pertaining to NT and since the OS is not supported tzedit is what we had to use. I'm surprised that it still is available.

Oh that's right. I remember having to use tzedit back when we still had Windows 2000 machines when the EPA pushed their changes through (for better or worse.) That's exactly what it is. Thanks.
