Even when running good ntp software, Windows is not the best time server. You should transfer time in the other direction. If you really want to do what you say you want to do, you will need a proper implementation of NTP on the Windows box. That means installing Windows 2003 with a recent service pack or installing the reference implemenation of NTP (basically the same source code as you run on Linux). If you take the first approach, you will need to provide a real time server for the domain controller, as Windows 2003, SPx is more honest about estimated errors (root dispersion) than a correct implementation of the protocol. If you use the reference version, it is possible to claim that the server knows the correct time, but this is strongly discouraged. It is also possible to attach some of the possible hardware reference clocks, I believe, although you need Unix or Linux for a full range. > about any error... ntpdate seems to work ok at command line with both ntpdate is deprecated, although it is much more tolerant of broken time servers - basically it doesn't plausibility check the results as well. > hosts... but if I type ntpd -d -q I get this error: Most of these are information, not error. > addto_syslog: bind() fd 4, family 2, port 123, addr 0.0.0.0, > in_classd=0 flags=8 fails: Address already in use This means that another instance of ntpd was already running. You should probably have looked at the relevant system log file to see what the first instance was saying, but I expect you will find it is rejecting the PDC due to an excessive root dispersion, which is best seen using the ntpq rv command for the association (use ntpq assoc to get the association numbers).
