Advanced Server Overview and Installation

Implementing WINS Name Resolution Services

Product Manual U7613-J-Z815-6-76

1. In the following illustration, a client name query

request

is sent first to the WINS server.

If the name is found in the WINS database, then the client can establish a session

based on the address mapping received from the WINS server.

Processing a Name Query Request

2. If the WINS server query is unsuccessful and if the client computer is configured as an

h-node, the client computer sends name query request packets (as broadcast messages)

in the same manner as a non-WINS-enabled computer.

3. If the name still cannot be found, the local LMHOSTS file is checked. (Included in the

search are any centralized LMHOSTS files referred to in #INCLUDE statements in the

local file.) On Advanced Server computers, the name table containing the mappings

from the names.cfg file normally is consulted at this point.

4. Advanced Server computers never use a HOSTS file or DNS for name resolution.

WINS servers accept and respond to UDP name queries. Any name-to-IP address mapping

registered with a WINS server can be provided reliably as a response to a name query.

However, a mapping in the database does not ensure that the related device is currently

running, only that a computer claimed the particular IP address and that it currently is a valid

mapping.
