In registry key:
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \Browser\Parameters
with this you can make one computer as a master browser and prevent the others from becoming master browser with IsDomainMaster="FALSE" MaintainServerlist="FALSE"
and make the machine you choose to become Master Browser with
IsDomainMaster="TRUE" MaintainServerlist="TRUE"

Stop Master Browser Election
Hello,
I currently build a new PC and upgraded to Windows 11. My old PC, I installed 6TB onto and am using for the home server.
I've hardwired everything together from the Google TV to the Router and Points and multiple PCs.
Currently, my new PC has been getting frequent and undiagnosed BSoD (this post can be found here. ) and while looking through the events logs, I'm also finding many network errors where it seems that the old PC (the Server) has taken over and declared itself the "Master Browser".
From what I've learned, this is leftover trash from the old networking days. How do I disable this?
The exact errors read:
Browser - "The browser was unable to promote itself to master browser. The computer that currently believes it is the matter browser is 2NDCOMPUTER"
NetBT - "The name "WORKGROUP :1d" could not be registered on the interface with IP address 192.168.xx.xx. The computer with the IP address 192.168.xx.xx did not allow the name to be claimed by this computer"
The Browser's computer name has been changed to "2NDCOMPUTER" because it is the name of the 2nd (the old) computer that I'm using as a server
The NetBT is two different IP address, but I have nothing named "WORKGROUP" on my network. This error happens every 5 minutes.
I wouldn’t mess with the router. You should be able to disable the Computer Browser service without any negative consequences. The service enables each PC to serve up a browse list for NetBIOS name lookups on the local network segment. If you disable it, the machine(s) simply won’t be able to serve up a browse list when other computers broadcast a NetBIOS name lookup request. For more info, check my post here: http://community.spiceworks.com/topic/274268-is-netbios-still-needed
Also be sure that the Computer Browser is enabled and set to Automatic on your DC(s). I think it’s disabled by default for server 2008 and up. If it’s enabled, the DC should win a browser election every time.
I have a windows network with 2 2008 R2 DCs at main site. I have a small remote office that has 1 XP computer always on the network and 1 XP computer that is sometimes connected to the network. The users at remote site connect to main network through VPN. There is no server at all in the remote office. Users do need to access information on the main network segment. I am getting the error “master browser has received a server announcement from computer Remote1 that it believes it is the master browser” and an election is held. I have been researching what to do about it. KB documents say to turn off the browser service on the romote1 computer or setup the router to not forward UDP packets. It would seem to me that turning off the browser server in the remote computer would be the better option, but are there any unintended consequences likely to result? If I were to stop UDP packets, what consequences would result there? I find it hard to believe that the browser service is the only thing that uses UDP. What is the best solution?
