Our Debian boxes worked just fine, but we had to patch a couple of older
RH7.3 boxes.

Same for me. Sounds like his host info changed and the server doesn't
recognize it. Time to hose the entry for his login in

Your tech worker isn't worth much. Windows XP SP1 couldn't be fixed
other than downloading and using tzedit.exe.

This means your machines NEVER update since SP2 is the current
version, and it automatically applied the time zone file.

We knew about this for nearly two years, yet almost everyone chose to
act a month before the change.

Luckily in my shop, we had all hundred+ computers patched and fixed,
as we still have a lot of Windows 2000 machines.

First do a Windows Update on your machine. That'll probably update the
time settings as well as about 200 or so KB's and SP's.
