I'm attempting to set up samba as a pdc on my network. I've followed steps that I've seen in numerous resources, used testparm to confirm my smb.conf is syntactically correct, used the smbclient command to connect from my unix box, and even changed domains to my new one with no problem. Now for the problems.

After switching over to the new domain (using xp pro as the client) I am prompted to reboot my machine. When I reboot, however, I'm greeted at the login screen with the following error

A duplicate name exists on the network (I know my computer name is unique because we use a router and I can see all computers connected)

Pressing on anyway, I select the samba domain from the drop down box and attempt to log in. I get the following

The system cannot log you on now because the domain UBERBEAST is not available

What do you do when your config file looks fine and you get no errors in the samba logs (I cranked it up to level 4). Any ideas would be greatly appreciated.
