More Information

In Windows NT 4.0 Service Pack 4, Microsoft added a new registry value to the TCP/IP service that allows an administrator the option of changing the hostname resolution order. By default, hostname resolution is performed by Domain Name Service (DNS) first, followed by NetBIOS over TCP/IP (NetBT), if DNS fails. With the use of this registry value, the order of hostname resolution can be reversed.


Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To change the hostname resolution order (between DNS and NetBT name resolution mechanisms), perform the following steps:
  1. Run Registry Editor (Regedt32.exe).
  2. Go to the following key in the registry:


    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
  3. On the Edit menu, click Add Value and enter the following value information:


    Value Name: DnsNbtLookupOrder
    Data Type: REG_DWORD
    Value: 1 or 0 (default=0, value of 1 causes NetBT name
    resolution to be attempted before DNS)
  4. Exit the Registry Editor and restart the computer for the change to take effect.
