Why? You don't need to mess with those registry settings directly in
almost all cases. Set them back to their defaults, and use w32tm alone
to configure the Windows Time Service.

You should use:

w32tm /config <your config info> /update to update the running Windows
time configuration

w32tm /resync causes Windows Time Service to throw out its frequency
correction history, and start fresh (similar to deleting ntp.drift on
an ntpd system). This makes it take longer to "settle down" to the
correct time... perhaps as much as hours depending on the intrinsic
error of your motherboard's clock.

Once configured, the windows time service should maintain +/- 16 ms or
so offsets after it figures out how fast/slow your motherboard clock is
running. If you don't yet have SP1 on that Windows 2003 server, I
suggest installing it, as there are many Windows Time updates included.
