I have a small domain with a PDC and BDC and 2 Terminal servers all on a NT 4.0 platform, about once a week I have one of my TS servers diconnect with the following event in the event viewer:
The master browser has received a server announcement from the computer MyBDC that believes that it is the master browser for the domain on transport NetBT_NETFLX1. The master browser is stopping or an election is being forced.

Data: Words

0020: 00000000 00000000
Any Suggestions?

Thanks,
JB

A browser election is a normal network occurance. An election provides a means to guarantee there is never more than one master browser present in a domain/workgroup. A master browser is elected in the following priority:

NT Server installed as PDC
NT Server
NT Workstation
other

A PDC (Primary Domain Controller) is automatically the Domain Master Browser even if "IsDomainMaster=TRUE" is set in the Registry on another NT Server in the domain.

If you are running workgroup servers (no domain controller) and want to force a specific server to be the preferred master browser, set the following registry entry on that server to TRUE:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters\IsDomainMaster

To prevent an NT Workstation or Server (non-PDC) from acting as a browser, set the following entry to No:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters\MaintainServerList

To prevent a WFWG system from acting as a browser, create and/or set the following statement in the [Network] section of System.ini of the WFWG client:

MaintainServerList=No. Other valid entries are Yes and Auto.

Windows 95 machines can only participate in a browser election if they are configured for File and/or Print sharing. This is accomplished in Control Panel / Networks. To set or check the browser settings, scroll the network Configuration for File and printer sharing for Microsoft Networks. Highlight this entry and click the Properties button. Select Browse Master and choose from Disabled, Enabled, or Automatic.

I would also check your subnet mask to make sure you have it entered correctly

and... also, look here. Remember.. a lot of things are related in NT. Even if it does not specifically say TS you can use your networking skills to apply the solution to best suite you. If it doesn't work, fine, redo it. It will not hurt anything. The BDC will take over browsing if the PDC fails REGARDLESS of this registry entry.

JB,

This message is normal, as explained by the first answer, upon a boot up of a LANMANAGER network. All windows networking platforms are based on this.
You don't mention what is causing the terminal server to stop. But it does not relate to this message.

Are you looking for a cause for the TS stoppage or the event viewer message?
