Time/Date difference between client and server?

I'm running Vista in a Win2000/Win2003 AD enviuronment.

It seems like the one Win2000 AD machine is a few seconds behind the rest of
the Win2003 AD Servers.

Though unfortunately the Vista machine sees the Win2000 AD machine as the
Logon Server, so when I login or access any other Server share I get an
error saying that there is a Date/Time Difference between the Client and the
Server.

trying to set the Vista machine's time to the Win2000 AD machine I get An
Access Denied message.

What Can I do to have my Vista machine point to a different AD DC for Login?

Thanks,
Scott<-
