This is where it gets difficult, I get the feeling that the original 
DC's are Windows DC's, not that this matters.

By default, All domain members (including DC's) are in the 
'Default-First-Site-Name' site and you cannot decide which DC to use, 
any of the DC's in the site will be used.

You can create a new site and move the Samba DC to this, then move the 
required domain clients to the same site. Now, by default, the clients 
in the site will use the Samba DC, unless it goes down, at which point 
any DC will be used.

Can I suggest an internet search on 'active directory sites'
