Information on the meaning of the various NetBIOS name extensions and their usage can be found in the “Microsoft Windows NT Resource Kit Networking Guide” .

The two most important aspects of the NetBIOS name service are registration and resolution:

●Registration is the process used to register a unique name for each computer (node) on the network. A computer typically registers itself when it starts.

●Resolution is the process used to determine the specific IP address for a certain NetBIOS name.

An Advanced Server for UNIX computer can use one or more of the following methods to ensure accurate name resolution in TCP/IP internetworks:

Broadcast name resolution

Broadcast name resolution is a NetBIOS over TCP/IP mode of operation defined in RFC 1001/1002 as b-node. This method relies on a computer making IP-level broadcasts to register its name by announcing it on the network and to query a name by asking all other computers in the broadcast area. Each computer in the broadcast area is responsible for challenging attempts to register a duplicate name and for responding to name queries for its registered name.

Broadcast name resolution has two major problems:

1.Broadcast messages typically do not pass IP routers, so computers that are on opposite sides of a routers are not reachable.

2.In a large environment, it loads the network with broadcasts, which every computer must handle.
