Have a NetWare 5.1sp 5 server that runs fine.

I just upgraded my client to 4.91.3, now when I try to either assign or
change a user password via Console One or NWAdmin it won't let me with
Error -319. I walk to a different machine with a lower client version (say
4.9sp2), and it works fine.

Can I roll the version of the Client back without going through the
Windows Restore? Or does anyone have a solution to this issue?

Thank you
