After about 10 to 15 seconds, NetBIOS gives up on the primary interface, moves to the correct tunnel interface, and starts to browse the Network Neighborhood.

Why can't I browse another client in a different tunnel?

Cause: If you are not using a WINS server, this is not possible because network browsing requires broadcasts from one tunnel to another.

Action: Use a WINS server to browse another client in a different tunnel. When the clients tunnel in, they should register with the WINS server. Be sure that the client you want to browse has Log onto Network enabled under My Computer > Dial Up Networking > Connection_Name.
