You may also wish to implement WINS so it doesn't use broadcast name resolution techniques. Also, if you have any WfWg machines, there was a fix years ago where they wouldn't relinquish a master browser role. MS issued a fix back in the 3.51 days. Similar situation, election wars, although it never took out Cat 5's or 7206's on the networks we used. Surely you're not doing broadcast flooding on the Crisco, are you? Alternatively, you can force one machine to be the master browser and the others to be backup browsers which pretty much obviates the need for an election. I would suggest http://support.microsoft.com and search for Preferred Master Browser. Eric ---"James D. Wilson" wrote:

I think you mean "browse master" and if your switches are falling apart by browser elections you probably have more serious problems on your network than NetBios traffic (however odorous it may "smell".) I'd take a good look at your spanning tree configuration and statistics on your switches. You could also be running into problems with bdpu traffic confusion in your switches spanning tree if you are also bridging and your bridge group priority 0 is not on your local side of your bridge group.

Discovered today that NT has the built in ability to drown your network and stomp on the routers cpu. Seems if someone sets up 2 NT domain masters or whatever that Netbios garbage is called, they attempt to "hold an election." The election is comprised of slamming every machine it can find and then every broadcast address it can think of with udp on port 137.
After a few minutes of it an RSP4 gets real tired and you start losing packets as well as the switches all falling apart after trying to forward the zillion mbits/sec of useless data.
Anyone else seen anything like this?
