Firstly, all MS Windows networking uses SMB (Server Message Block) based messaging.
SMB messaging may be implemented with or without NetBIOS. MS Windows 200x supports
NetBIOS over TCP/IP for backwards compatibility. Microsoft is intent on phasing out NetBIOS
support.

Samba implements NetBIOS, as does MS Windows NT / 200x / XP, by encapsulating it over TCP/IP.
MS Windows products can do likewise. NetBIOS based networking uses broadcast messaging to
affect browse list management. When running NetBIOS over TCP/IP, this uses UDP based messaging.
UDP messages can be broadcast or unicast.
