5.1.3 Configuring NetBIOS Name Resolution

NetBIOS name resolution is the process of successfully mapping a NetBIOS name to an IP address.

How name resolution is carried out on a Advanced Server for UNIX computer depends whether the computer has been configured as a WINS client (with the help of the file wins.cfg) or not.

If WINS is not enabled, name resolution works in the following manner (“modified b-node” ):

1.Check the name table

2.Try broadcasting

To find a particular name, the Advanced Server for UNIX computer first checks its internal NetBIOS name table. This table contains

●local names

●a name cache consisting of mappings from recently received NetBIOS datagrams

and

●a list of static mappings from a names.cfg file.

If the name is not found, the computer sends name query request packets (as broadcast messages) on the local subnet. These broadcast messages normally cannot pass IP routers.

If WINS is enabled, name resolution works in the following manner (h-node):

1.Try a WINS server

2.Try broadcasting

3.Check the name table

To find a particular name, the Advanced Server for UNIX computer first queries its primary and/or secondary WINS server. If the WINS servers are not available or unable to map the name to an IP address, the computer switches to b-node but continues to poll for the WINS servers and switches back if a WINS server becomes available. The NetBIOS name table containing local names, a name cache consisting of mappings from recently received NetBIOS datagrams and a list of static mappings from a names.cfg file is consulted as a last resort.
