VMS NFS server can't handle SunOS V4.1 client

[elsen at esat.kuleuven.ac.be]

  This problem concerns VMS NFS (UCX V1.2) and SunOS V4.1 ,but since it
  basically deals with NFS I decided to post it in this newsgroup,
  that is to keep everyone happy... :-)

  After upgrading a SparcStation to SunOS V4.1 (coming from
  V4.0.3) we are no longer able to mount file systems residing on a 
  VMS NFS server running Ultrix Connection Software V1.2 / VMS V5.3-1.
  
  The NFS server bombs out with:

%%%%%%%%%%%%  NFS$SERVER       26-JUL-1326 11:16:46.76  %%%%%%%%%%%%
%UCX-E-NFS_NOPROG, requested RPC program unavailable
-UCX-S-NFS_RPCHDR, xid = 928DAD26  program = 100005  version = 2  procedure = 0
-UCX-S-NFS_CLIENT, uid=0  gid=0  host_name =         ^^^^^^^^^^^


  I am by no means an NFS expert but the accompanying message in the
  UCX System Manager's Guide tells me that this happens when there is
  a mismatch between NFS versions running on the server versus the client.

  Could someone elaborate some more on this ?
  What NFS version does UCX V1.2 implement ?
  Is Sun OS V4.1 NFS too elevated for UCX V1.2 or vice versa ?
  Will UCX V1.3 be able to handle SunOS V4.1 client  systems ?

  We will probably delay any further upgrades of other Sparcstations until
  I got some more insight into this.

                           Thanks for any  info,
