I had an similar problem on my net consisting of 2 DECstation 5000 and
an IBM RS/6000 when mounting via NFS on one of the 2 DECstations. I
received the same error message from the ULTRIX-System. I don't
remember exactly what I have done to resolve the problem but the
following considerations may help you:
  -- NFS needs the original hostname of the machine not one of
     the aliases defined in the /etc/hosts-file
  -- There may be a problem concerning uppercase-letters in the
     hostnames. I set the hostname of one DECstation to a name
     consisting only of uppercase letters (installation procedure).
     If I remember correctly, after changing the hostname from
     uppercase to lowercase-form the problem was resolved.

If you will resolve the problem please send me a short message with
the exact solution to my personal email-address (RA04 at DKAUNI2.bitnet)
so that I can add a note to my problem-solution-list.
