Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base: Q256986 Description of the Microsoft Windows Registry 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. STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Windows XP. REFERENCES ========== For more information about the EnableDNS method, see the MSDN library documentation about WMI and the Win32_NetworkAdapterConfiguration class.
