[Samba] Access Denied using Server Netbios Name

[Dennis Clark]

Using Ubuntu 6.06.1, Samba 3.0.22, VMWare on Win2003 server.
 
I can connect using with admin user and ip address, but using admin and netbios name prompts for password and results in access denied.  WINS is enabled in Samba config.

Does Vmware or Ubuntu introduce weird problems or is something else going on?  Running the net stat command results in error 5 trying to resolve netbios name.
