Excessive Broadcast traffic on Lan

Since the installation of 50 NT servers on the Lan, broadcast traffic has increased exponentially.

We have 42 individual networks, some on the routers, and a major 800 user Fast Ethernet segment on Layer three switches.

Is there any broadcast traffic that can be totally eliminated using WINS servers (or any other means), or any time settings that can be changed on the NT/95 boxes that would make a substantial reduction in broadcast traffic?

You can eliminate netbios name registration broadcasts by using WINS and setting client2 to using P-nodes (point name registration).  The default is H-node (hybrid), which tries to register first by contacting WINS servers via IP, then broadcasting.  P-nodes don't broadcast, only use IP to WINS.

This is a good answer as far as it goes. I already knew and have implemented this, I should have stated this as part of the question.

Another source of broadcasts is associated with browsing.  Every 12 minutes, machines broadcast resources available for sharing.  If a machine shares no resources, this broadcast does not occur.  Turn off file&print sharing for Win95 clients and remove the Server service for Workstation clients.  Note that you will not be able to map drives, etc, to these clients.
