Before you edit the registry, you should first make a backup copy of the registry files (System.dat and User.dat). Both are hidden files in the Windows folder. SUMMARY ======= This article describes how to disable NetBIOS name resolution on a domain- name system (DNS) while retaining other DNS functionality. MORE INFORMATION ================ When Windows 95 tries to resolve a NetBIOS name using a NetBIOS name server, it first checks a Windows Internet Name Service (WINS) server, and then checks a DNS server. WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. NOTE: For information about how to edit the registry, view the Changing Keys And Values online Help topic in Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry. To disable NetBIOS name resolution on a DNS server, change the string value EnableDNS in the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP from 1 to 0.
