Joining Domain Problems, first time

[bretd88]

I have setup a new server with Linux Enterprise and Samba 3.09137.

I am missing a step some where.
I am not able to join the domain with any machine(all machines are XP that were on the previous samba server)
When attempting to join domain from Windows System properties I get the following,
I put the Domain name in and get a login prompt and get this error with root user
"the name could not be found"
With the user name Administrator I get "access is denied"
I have tried a variety of commands and switches with smbpaswd but I am obviously doing something wrong.
Both users Root and Adimistrators are users in Linux and samba and should have admin rights.

My Smb.conf is as follows
# Global parameters
[global]

The problem was the Linux firewall was blocking me from joining the domain.
