SYMPTOMS

If you use Windows Management Instrumentation (WMI) on a new (or "clean") installation of Windows XP to turn on Domain Name System (DNS), calling the EnableDNS method of the Win32_NetworkAdapterConfiguration class may generate return code 94 ("Path, file, or object not found").

CAUSE

This behavior occurs if the Windows XP-based computer does not contain a NetCfgInstanceId string value under the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\0000

If this string value does not exist, the EnableDNS method stops processing prematurely.

RESOLUTION

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 work around this problem, create a NetCfgInstanceID string value under the registry key that is mentioned earlier in this article. You can leave the data value of the new string value blank, or set it to any value.
