Example of Clients and Servers Using WINS
In this illustration, Client A is a not enabled for WINS, Client B is enabled for WINS, and
Client C is a WINS proxy agent. The following table shows the typical steps that Client A
and Client B take when resolving names.
Client A (Non-WINS) Client B (WINS)
Client A sends a query (as a
broadcast message) for Client X’s IP
address. Client X (not shown) is not
on the local subnet.
1
Client B queries the WINS server for Client A’s IP
address.
Client C (WINS proxy) intercepts the
broadcast message and sends it
directly to the WINS server.
2
The WINS server responds directly to Client B with
Client A’s IP address.
3
The WINS server responds directly
to Client C with Client X’s IP address. If the WINS server is unreachable, the query fails.
Client B switches to b-node and sends the query as
a broadcast message on the local subnet.
Client C responds directly to Client A
with Client X’s IP address. Client A receives the broadcast and responds
directly to Client B.
1 If Client X was on the local subnet, it would respond directly to Client A’s query.
2 Client C may already have the requested information in cache. If so, Client C responds directly to Client A
without going to the WINS server.
3 Both examples assume that the requested information is available in the WINS database on the server.
