Ya, I too have read that, and some who have already flamed me in personal email obviously don't know the full capabilities of Cisco's IP helper forwarding on the NetBIOS UDP multicast packets, which also allow browsing on the network from multiple subnets without a WINS proxy on EACH subnet. Just to clarify, my question here is for opinions on either implementation, I KNOW how to implement them and that both will work. I'm looking for an experienced answer on this one.

It clarified stuff for me that the MS dox left very muddied. > -----Original Message----- > From: [email protected] [mailto:[email protected]]On Behalf Of > Carter, Gregory > Sent: Tuesday, April 25, 2000 12:26 PM > To: '[email protected]' > Cc: '[email protected]'; '[email protected]' > Subject: WINS Proxy vs. Cisco IP Helper > > > > Greetings! > > I have a bit of a philosophical question regarding the use of > a WINS Proxy > versus using Cisco's IP Helper to forward UDP datagram > packets off to a central > WINS server.
