SYMPTOMS
In Windows 95, Windows 98 and Windows 98 Second Edition (SE), several fields in the Windows Management Instrumentation (WMI) Win32_NetworkAdapter class are not populated. These fields include AdapterType, Index, MACAddress, and TimeOfLastReset. In addition, instances of the Win32_NetworkAdapterSetting association class are not generated in these versions of the Windows operating system.

CAUSE
This problem occurs because in these versions of the Windows operating system, the Win32_NetworkAdapterConfiguration class obtains its information from the device driver (TDI kernel adapter) whereas the Win32_NetworkAdapter class obtains its information from the system registry. The registry-represented adapter does not contain data that is relative to the AdapterType, physical address (media access control), or TimeOfLastReset; therefore, these fields are not populated. The Win32_NetworkAdapter Index property is not populated in these versions of Windows because it is not possible to associate the Win32_NetworkAdapter and Win32_NetworkAdapterConfiguration classes.

STATUS
Microsoft has confirmed this to be a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION
In Windows 95, Windows 98 and Windows 98 Second Edition (SE), you can obtain the media access control address (MACAddress) for a network adapter from the Win32_NetworkAdapterConfiguration class.
