Master browser problem...

Getting this error in our domain controller from the ISA server that thinks it's the master browser

The master browser has received a server announcement from the computer ISASERVER that believes that it is the master browser for the domain on transport NetBT_Tcpip_{54BBEA32-9A77-4EDA-. The master browser is stopping or an election is being forced.

Read a few things but still not sure why this is happening and how to fix it...

ISASERVER is w2003? and, has a VPN access configured?

My standard "post" in these questions:

See here:




The second link, click on the link for "How computer browser service works"

cut/paste of some of the text:

Browser elections occur to select a new master browse server under the following circumstances:

• When a computer cannot locate a master browse server.
• When a preferred master browse server comes online.
• When a Windows-based domain controller starts.
• When a back-up browse server cannot contact the master browse server to obtain updates to the browse list.

Browser Election Criteria

Election Criteria Value Windows Election Field
Windows 98
Windows XP Professional, Windows 2000
Windows Server 2003, Windows 2000 Server
Election version
Version-specific criteria
WINS system
Preferred master
Running master
MaintainServerList = Yes
Running backup browse server


So basically i just need to make sure that the IsDomainMaster value on the domain controller is set to TRUE then that should be ok ?
That will force the DC to be the Domain Master browser...yes.

However, that won't necessarily stop the ISA server from starting a browse election, but it will lose the election.

On the ISA server, go here:


And make sure that MaintainServerList is set to No

This will prevent it from even wanting to be a browser list server.

My "personal" way of doing things is to disable the computer browser service on all workstations and member servers, and only let the DC's hold browser lists, but don't do this unless you are certain that's how you want things setup and that you don't need the browser service running on those other servers.
