Hi all
I have Windows 2000 server as primary and Windows Nt 4 as Backup Domain controller.
When i check event viwer for every 40 mins i find error meaasge name Rdr and error number is 8003 and its discription is like this
" The master browser has received a server announcement from the computer that believes that it is the master browser for the domain on transport NetBT. The master browser is stopping or an election is being forced."

How can i stop this error.

I am asking the same question myself, but I have seen this error come and go all by itself over the past two years. It eventually goes away but in the mean time it prevents the use of mapped drives. they say to check the subnet masks, but mine are all the same.

Check the error and see if it specifies which machine is forcing the election. Sometimes the error will name the machine causing the problem. If it is an XP machine you will need to disable the master browser via a registry hask or via the local policy setting. If it is a win 9x machine there is a setting in the network settings you will need to disable. Hope this helps.

If you have any windows machines on a separate subnet you will get browser election wars like this if certain broadcasts are forwarded on the router. I stopped this by adding the following to all my Cisco router configs:

ip classless
no ip forward-protocol udp netbios-ns
no ip forward-protocol udp netbios-dgm
