Use of raw SMB over TCP/IP (No NetBIOS layer) can be done only with Active 
Directory domains. Samba is not an Active Directory Domain Controller: ergo, 
you can not run Samba as a domain controller and at the same time NOT use 
NetBIOS. I am rectifying the documentation so as to remove all doubt.

Also, WINS and NetBIOS node-type are features of running NetBIOS - the 
documentation was just plain crazy - it was wrong and misleading and is being 
fixed.
