I described how to configure an authoritative time server in Windows 2000 and how to configure the Windows Time service on the Windows Server 2003 forest root PDC emulator.

In Windows 2000, I used:

net time /setsntp:192.5.41.209,192.5.41.41

In Windows Server 2003, I used:

w32tm /config /syncfromflags:manual /manualpeerlist:192.5.41.209,192.5.41.41
w32tm /config /update

Where 192.5.41.209 is the NTP server ntp2.usno.navy.mil  and 192.5.41.41  is the NTP server tock.usno.navy.mil

To view the US Naval Observatory Master Clock time, use http://tycho.usno.navy.mil/cgi-bin/timer.pl
