I just had the same symptom after upgrading from v2 to v3.0 of PC-NFS on
my machine, bobcat.bbn.com.  After a fair amount of fooling around, it
turns out that version 3.0 mucks around with the name of the PC before
sending it out in the mount request to the server.

In version 2, the request was sent from "bobcat.bbn.com".
In version 3, the request is  sent from "bobcat".  No matter how you
try to configure it.

A workaround is to have "bobcat" instead of "bobcat.bbn.com" in the
netgroup file on the servers.  I'm not thrilled with that solution.

This is the old "fully qualified or not" issue in Sun system
administration.  For reasons lost in history and which are not
about to be changed, we have fully qualified $HOSTNAMEs and
netgroup files and so on in our department.  Version 2 allowed
either way (as long as the total hostname was short enough).
Version 3 doesn't.

I don't know whether this is your problem, Brian, but check it out.
I have an open problem report to Sun on this.  No fix yet.
