nwLoginError is 81

Since I implemented cifs, it has been unreliable. Sometimes it works and sometimes it doesn't.

My user account1 can't use cifs:

account0@workstation:~> smbclient //netscan.company.edu/vlun10 -U account1
session request to NETSCAN.LAFAYETT failed (Called name not present)
session request to NETSCAN failed (Called name not present)
Password:
session setup failed: NT_STATUS_LOGON_FAILURE
account0@workstation:~>

Neither can my user account0:

account0@workstation:~> smbclient //netscan.company.edu/vlun10 -U account0
Error connecting to 111.11.11.11 (Connection refused)
Connection to netscan.company.edu failed (Error NT_STATUS_CONNECTION_REFUSED)
account0@workstation:~>

So I restart my cifs service:

myserver:~ # rcnovell-cifs restart
Shutting down Novell CIFS Service done
Starting Novell CIFS Service done
myserver:~ # tail -f /var/log/cifs/cifs.log

The users have universal password and the cifs password policy set.

I saw a similar problem with similar errors, (See link below) only I'm not running a cluster and I patched my server about two weeks ago.
