[CentOS] ntpd appears to not be able to query ntp servers automatically?

After reboot, one of my servers running CentOS5 no longer keeps its
clock synced automatically. ntpd is running and I don't see anything
weird being logged. If I kick off ntpd with 'ntpd -q', it will sync the
clock. However, if I just rely on ntpd started with 'service ntpd
start', syncing does not happen.
I previously had:
# Undisciplined Local Clock. This is a fake driver intended for backup
# and when no outside source of synchronized time is available.
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
and noticed that ntpd would fail down to using the undisciplined local
clock if I checked with ntpstat. I commented those out, and now ntpstat
time server re-starting
polling server every 64
Any idea as to why ntpd -q will sync, but otherwise the clock will not
stay in sync even when the local clock drifts by several minutes? It
worked fine prior to reboot.
