SUMMARY: Solaris 2.5 NFS, FTP Software NFS, MS-Mail

I received some tips from "Chan Cao" <> and
"Kai O'Yang" <> but didn't find a
solution. We found out that the problem is due to some differences
between Solaris 2.3 & 2.5 in the way the NFS lock manager works.

Our limited testing (too many users screaming) shows that
OnNet 2.1 (the latest version) works but OnNet 1.x doesn't.

We switched back to Solaris 2.3 for now until we can do more
testing to make sure OnNet 2.1 really works and will upgrade
our client pc's before attempting the OS upgrade again. Good
thing we still have Solaris 2.3 on our backup disk which made
the OS back-out fairly painless.
