Implementing WINS Name Resolution Services

Product Manual U7613-J-Z815-6-76

1. In the following illustration, a c lient 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 s ession

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 ca nnot 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 m appings

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

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

WINS servers accept and respond to UDP name queries. Any name-to-IP addre ss 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 cur rently

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

mapping.
