As far as getting all routers to see each other in Network Neighborhood,
using ip helper-address is the cisco-centric fix. Per Microsoft, the fix is
to use a domain model instead of a workgroup model.

Ip helper was meant to forward UDP broadcasts, including but not limited to
bootp. By default, there are a bunch of ports that will be forwarded (tftp,
netbios, bootp, etc.), and you can add more ports (or remove existing ports)
to the list with the ip forward-protocol command.

By using this for windows browsing, though... you're going to consume a lot
of your WAN bandwidth, because all windows netbios traffic is going to be
forwarded in all directions, not just the master browser elections.

Ken, what you wrote should have worked. The theory is sound, anyway. If
you forward me your configs, maybe we can figure out what was missing.
