You can use tcpdump on the nocol server to get some clarity on what's
goin on, i.e.
oink|~#tcpdump -s 256 port ntp
tcpdump: listening on hme0

the first to packets are my own ntp daemon the other are from the nocol
server i guess. Also you can use ntpdate -d ntp-server to see if you
can retreive ntp time info (but i think you have to kill the xntpd first
if it's running on the system from where you want to try the ntpdate.
good luck! Ewald...
