Is the NFS volume exported to specific servers or to the world? It
sounds like there is a hostname mismatch. Either...

1) the NFS export does not grant permission to the AIX51 server, or

1) the Solaris server has a hosts file entry for the AIX51 server that
doesn't match the name in the export list. Either the AIX51 server
will be in there with some sort of shortened or aliased name or
perhaps the IP address once belonged to an older server that had an
entry but has now been recycled into the new AIX51 server, or

2) the name in the export list doesn't match exactly what gets
returned from DNS, or

3) the DNS entries are messed up such that the forward and reverse
lookup of the name and IP address of the AIX51 server do not return
the same results.
