Had no replies to this one. Seemed to be a pcnfs
authentication mismatch, although reinstalling pcnfs, and
even restoring the daemons from the 2.5.1 backup, did not
work.

Eventually found that the line we had in /etc/dfs/sharetab, :

share -F nfs -o rw=pc_host_name /data

was incompatible. Removing the host name, thereby sharing
to ALL systems, fixed the problem, although access has
been thrown open.

There was no hostname resolution problems, ping worked
fine, seemingly no logical explanation.

Original post:

Just upgraded a Sparcstation 20 from Solaris 2.5.1 to
Solaris 2.6. All recommended patches installed.

This system shares a directory with a PC via PC-NFS pro
2.0

After the upgrade, the PC can still mount the files, but any
attempt to access files from the unix box logs this message
to /usr/adm/messages:

WARNING: nfsauth: RPC: Unitdata error

and the PC locks up.

I searched the archives and found references a year old that
reported this as a performance problem. We only have one
PC using this NFS link and it has only become a problem
after the upgrade.

Any help is appreciated.
