Issues with Master Browser Server

Dear All,
I have faced system failure from few days which caused all servers to be un reachable and I had to restart all of them (VMs).Domain contollers were up and reachable with no problems.

After that I started to recieve Events 8021 and 8032 on the servers on the events i can see that the Master Browser Server mentioned is one of the test machines available on NW.

I am working with Windows server 2003 AD, All server are either Windows Server 2003 or Windows Server 2008

I dont know what I should do to let everything go back to normal...and why this clinet was selected ?

Kindy advice

Go to the machine that is 'mistakenly' been advertised as the master browser and do the following;

Take note of what <clientname> is and go to that machine

Start > run > regedit {enter}
Navigate to

Modify the MaintainServerList and/or the IsDomainMaster key to a value explained here:

MaintainServerList No This PC will not participate as a browser.

Make sure the following DOES NOT exist

IsDomainMaster True Designate this PC as the preferred master browser.



I did something...i turned off this test machine, and checked the servers with browstat.exe and found that the master browser becme another server.

Should the master browser be the ssame as the DC ?


Kindly note that I have WINS server in the network

Master browser role is a roaming workgroup feature, not a domain feature. The role will auto move after a voting system is used to determine who is availble to take over the role. Ideally, no client machines should be used as a master browser and this can be controlled using registry entries (see above).

Best to not run the Browser Service at all on client machines, that is deactiveate the corresponding service on clients. With WINS it should not be used, but doesn't harm to have it running on server machines.


Thank you all...I am stopping the computer browser servcie and everything is working fine
