Sorry this took me so long to post but since I still don't know the solution
there has not been much to summarize. Some of the suggested solutions were

1. boot single user and re-run ypinit -m

2. set a default route prior to starting ypbind

3. make sure the /etc/defaultdomain file is correct and corresponds to
   the domain for the yp maps in /var/yp

Unfortunately, I had already tried 1 and 2 and everthing was correct with
regard to 3.

The only changes I had made to rc.boot and rc.local was to set the correct
broadcast address (host part all 1's) and comment out some things we don't
want. Further investigation showed that ypbind was broadcasting the correct
address but the packet length was 112 bytes (etherfind -r). I only mention
this as it was the only difference I could see between the packets from
ypbind which worked on other machines and those from the machine which would
not bind to a yp server.

Anyway, I solved the problem by reinstalling and then rebooting after every
change to rc.boot and rc.local in an effort to discover which change caused
the problem. But this time the problem did not arise - not sure why. However
I can reproduce the problem by booting single user, hand-configuring the
interface, setting a default route, starting the portmapper and then ypbind i.e.
the same things rc.local does.

If anyone can shed some light on this, I am still interested. Thanks to those
who replied to the initial posting which follows
