How to disable servers from becoming browser servers
As we mentioned, all domain controllers must be singlehomed for browsing to operate correctly. All domain controllers in a domain are by default browser servers. To disable multihomed Windows NT servers from becoming browser servers: 1) go to click Administrative Tools>Services>the Properties of Computer Browser, and then click Manual. 2) Use Registry Editor (Regedt32.exe) to edit the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters\MaintainServerList and change the value of this key to false NT and in Win 2000, instead of the value false, use the value, no. NOTE: The registry settings in this article do not work on a Windows 2000 DC if it is the PDC emulator.
