I am have a problem joining my win2k client onto a domain.
I have samba running as a PDC. Here is my smb.conf file

# /etc/samba/smb.conf

when i try and join the client to the domain, I get an error saying "The specific domain either does not exist or cannot be contacted".

when I run teh net use \\server\share command I get the following error - "error 51 has occurred. the remote computer is not available".

Please can someone tell me what i am doing wrong. I repeat cannot join a client to the domain.
