We had the problem solved before any answers arrived, thanks anyway to
rlyle@nl.oracle.com, paulo@dcc.unicamp.br, and a third person whose
message I happened to delete.
The prize for the best answer goes to rlyle (s.a.):

It WAS the UID 0 but I can't comment on UCX vs. TCPware, UCX did the job
in the end.

The VAX administrator writes:
+ It turned out that the NFS-server on the VAX expected UID -2 and GID -2,
+ though a proxy with thet right xID's was present. When the default
+ UID and GID were changed to the values of "root" on the sun, it was
+ possible to mount the VAX's NFS-file-system on the sun. I suppose this
+ kind of problems is due to my lack of experience with unix and network-

I just got another message from PHIL_LORGAN@NYMCS.CV.COM which I just include
(don't really want to get into VAX details too much now that it works):

Hope that helps people who have the same problem,
