How about issuing the command "ntpq -p" on the server that's not
synchronizing and posting the output? That will tell us which internet
servers it can see, if any. My first guess would be that if it's not
synchronized, it's because it can't establish contact with anything to
synchronize with.
My second guess is that it might fail to synchronize because its own
local clock is too far off. If it's more than five minutes off, set the
local clock to approximately the correct time before starting ntp.
Finally, it might be failing to synchronize because your local clock is
drifting too fast. If the undisciplined local clock gains or loses too
much, it will never synchronize and stay synchronized. The limit is
about 500 parts per million.
