NetBEUI is being replaced because it has a small scope and is not
scalable to large networks, not because of broadcasting. NetBIOS orders
the broadcasts, NetBEUI just does what it's told (as does TCP/IP).
There are many modes of operation, you'll need to read the RFC's for a
full explaination. Look at:

However you have it set up is how ALL MSNET clients (DOS box or GUI) will
BTW: NetBIOS can sit atop TCP/IP *AND* NetBEUI. It's not exclusive.
If you are really interested in the workings of NBT (NetBIOS over TCP/IP),
read the two RFC's listed above, they should shed quite a bit of light on
the subject. Expirience using it helps too.
My original point was that if you have MS clients already, adding an SMB
server (NT or Samba, doesn't matter) will not increase the broadcast
traffic from the clients. (Could actually decrease it.)
