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.

Client C responds directly to Client A 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 A receives the broadcast and responds directly to Client B.

1If Client X was on the local subnet, it would respond directly to Client A’s query.

2Client C may already have the requested information in cache. If so, Client C responds directly to Client A without going to the WINS server.

3Both examples assume that the requested information is available in the WINS database on the server.
