[Samba] "The Domain THUNDER is not abaliable"

[Dan Saul]

Good day.

I am relatively new with samba, I can get a single server
configuration of samba to work. However now I am trying to get single
sign ons with roaming profiles to work. I can join the domain without
problems. However when I restart and then type THUNDER\dan and my
password into the login screen (as the domain entry box does not show
up) I get the error "The system cannot log you on now because the
domain THUNDER is not avaliable.".

This error still happens even though I can browse the file server
portion of the server.

My goals with this server are to have my login accounts set on the one
server and logged on to by Windows XP Pro, and Mac OS X eventually.

The following is my smb.conf file, it is mostly a copy of one I found
in a HOW-TO on the internet, most options I do not understand.

[global]

   netbios name = %h
   server string = %h

   delete user script = /usr/sbin/userdel -r %u
   add group script = /usr/sbin/groupadd %g

   passwd program = /usr/bin/passwd %u
   passwd chat = *Enter\snew\sUNIX\spassword:* %n\n

   passwd chat debug = yes

If you require any other information I will be more then happy to
provide it, simply say the word.

Thank you for your time, it is much appreciated.
