Your NTP server running ntpd therefore uses its own local clock as its
reference time, right?
You should have the following lines included in your ntpd.conf:
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 12 # local stratum
You can change the stratum level of the "local clock" reference with
that fudge line (just edit the "12").
I am not sure which stratum the W32time service considers for itself,
therefore you might need to try out a few values. You should try to
avoid a better (=lower) stratum level than 10 for a system which uses
its own, unsynchronized local clock as the time reference. If you need
it to be lower than 10, you should be aware of the fact that this can
lead to ugly effects and bad timekeeping on the clients if you ever
introduce synchronized NTP time servers into your network and forget to
reconfigure your server.
