Group names:
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.
