[Samba] 3.0 to 3.2 upgrade

[Eric Lopez]

Hi Everyone,
I am using Debian Lenny, and recently upgraded from 3.0.2 to 3.2.5. 
Everything use to be working fine, now I keep getting this error:
:~# smbclient -L 192.168.64.20  -U test
Enter test's password:
session setup failed: NT_STATUS_INVALID_WORKSTATION

I have been looking around the Internet and all references to this error 
are for older versions (2.x), so no longer applicable, plus every thing 
was fine with 3.0.2. Any ideas as to where I could look for clues?
Thanks in advance for your comments,
