I would like to personally know if this only happens with the object files
residing on the DECStation. Is it OK with the Sparcstation used as 
the source server? Nota Bene the NFS code is pure Sun NFS code, so the
implementation should be the same as the Sun specs.

Most of the problems I've seen with NFS are Yellow Pages configuration
problems concerning access. If in this case you have access to the binaries/
object code, and something does not work, is there maybe some dependencies
of files that have to be accessed from other filesystems? As you see
it's quite hard to define the problem without having a little bit more
evidence and configuration information.

Well, back to work.
