samba - Sep 2003 - Samba cannot find my domain!

Hi
I am trying to connect my linux desktop to a windows NT 4.0 Server SP6a 
running as a PDC. I can mount drives from that computer but I cannot 
join the domain. Using the following comand:

# smbpasswd -j FUCELL -r PDC -U ivan


I get
Error connecting to PDC
Unable to join domain DOMAIN.

I have followed the winbind documentation. Could there be settings on 
the PDC that could/should be changed or have sould I check for any 
smb.conf setting problems?

Any help will be greatly appreciated

Ivan
