It was a Win2K3 client with its clock hours off connecting to a Samba
server (with Win2K3 domain controllers at the back end) - with correct

It was a nasty case. The problem was that it was a CentOS4 server
running Win2K3 as as virtual server under VMware. There is a bug/issue
between current vmware-server instances and 2.6.9* series Linux kernels
that means VMware can't emulate "time signals"(?) correctly. End result
was that even though the Win2K3 client had a ntp agent installed, it was
unable to keep it's clock in sync. We also have an identical issue with
running virtual Linux in the same environment. The syslog is filled with
ntp errors about being unable to slew the clock.

So we're going to run VMware under Fedora instead - at least that kernel
is less than 2 years old ;-)
