Master browser on a LAN...

I have a Windows NT 4.0 Server as a PDC, and Windows 95 clients authenticating with the PDC.

I am getting this RDR error message in the event log:

The master browser has received a server announcement from the computer JOSIE that believes that it is the master browser for the domain on transport Nbf_El90x1. The master browser is stopping or an election is being forced.

The Event ID is 8003.

First, what is the problem?
Second, what is master browser and where do you set it/view it on the server and on client workstations?
Third, what is the diff. between master browser and the service in NT called computer browser?

Hi loyaliser

1. I believe the problem is that both computers are fighting over who has control of the list of domains, servers and computers on the network and the authority to distribute this information upon request of a logon computer. If two computers are doing this, the logic of the operating systems shut down Master Browsing and forces an election of one computer. The master browser does not have to be the PDC but it will sychonize with the pdc every 15 minutes by default. This will occur only after the election takes place. The PDC should by default be elected the Master Browser or the backup master browser.

2. The Master Browser is the computer that has the authority to maintain the list in question 1. To find out if your server is a Master Browser check the registry under


This setting will be false or no, even if the computer has been elected the Master Browser. You can change this parameter by changing the value to true or yes. this will force the server to be the master browser everytime. Also you can disable broswer parameters in Windows 95 by going into Network Neighbourhood and if you have file and print sharing on for MS clients, change the property from automatic to disable.

3.  The computer browser service is the part of the NT system that builds the list of domains, servers and computers. While the Master Browser is the actual computer that holds the list.

If you are not experiencing problems, then the elections are taking place, but if you are having issues, try the solution in number 2.

I hope this is the answer you are looking for ...

Oh.. any you can see if you server is enabled as a Master Browser if you look under the Network Services...
