NetBIOS name resolution nodes.

NetBIOS name resolution nodes define the order of the methods it uses for name resolution.

Note: regardless of which node the computer is using, the computer will always check the local NetBIOS name cache first, and the LMHOSTS file last.

H-node	Hybrid node. The computer will first query the WINS Server for the mapping, then if not successful, will use (up to) 3 b-node broadcasts. By inserting the IP address of the WINS Server in the computer's network properties, it defaults to H-node.
M-node	Mixed node. The computer will first use (up to) 3 b-node broadcasts, then if not successful, will query the WINS Server.
P-node	Point-to-point (aka Peer-to-peer). The computer will only query the WINS Server.
B-node	Broadcast. The computer will send out a broadcast to all computers on its local network to have the computer with the requested name send back a confirmation with its IP address. B-node is the default node method for non-WINS clients.

To alter which node your computer uses, you will need to make the proper changes in the DHCP Server. You will be prompted to give a value for the node you wish to use.
