WINS uses UDP unicast (directed UDP) which is routable. What you have referred 
to is known as "NetBIOS helper agent" - a router configuration option that 
can perform forwarding of NetBIOS UDP broadcasts. This option is a VERY bad 
thing and is totally unecessary if WINS is correctly configured and if 
clients are working as they should.
