You need to add lines here:
restrict time.nist.gov mask 255.255.255.255 nomodify notrap noquery
restrict ns.arc.nasa.gov mask 255.255.255.255 nomodify notrap noquery
restrict tick.usno.navy.mil mask 255.255.255.255 nomodify notrap noquery

# Undisciplined Local Clock. This is a fake driver intended for backup

# default stratum is usually 3, but in this case we elect to use stratum
# 0. Since the server line does not have the prefer keyword, this driver
# is never used for synchronization, unless no other other
# synchronization source is available. In case the local host is
# controlled by some external source, such as an external oscillator or
# another protocol, the prefer keyword would cause the local host to
# disregard all other synchronization sources, unless the kernel
# modifications are in use and declare an unsynchronized condition.

Wasn't there a line:
server 127.127.1.0 # local clock
here originally?
fudge 127.127.1.0 stratum 10
Cheers, Paul.
