[Samba] SMB Help

[Christopher M Bailey]

Hi All,

I'm trying to configure a Samba PDC, and for some reason I can not get
any windows PC to join the domain, however they can see the shares.
Strange thing is that under Webmin I can not see root as a smb user and
when I try a smbpasswd -a root I can enter the password, but it still
wont add a smb user.  

Samba version 3.5.4-0.70.el5_6.1
smb.conf below

TIA 
Chris
