About a week ago I posted this:

As it turns out I had an inspiration and fixed the problem. It turned
out that I had misconfigured the ptp devices (these are things to do
with the Sun Internet Router) so that I had a single ptp configured
for two links. The strange thing is that the network still worked, I
could ftp, rlogin and so on but YP just would not work.

Thanks to 2Lt David Hightower who sent the following suggestion:

Is the domainname correct for both? We had a similar problem, where one
of our slave servers' /etc/defaultdomain listed a different domain....
