https://community.hpe.com/t5/windows-server-2003/wmi-msndis-macoptions-class/m-p/4442898#M5627 The root\WMI namespace contains a MSNdis_MacOptions class with NdisMacOptions property (ULONG32) does anyone know what the possible values mean? One google search indicated that the lowest 8 bits indicated the Network Card duplex setting. If it does this would resolve a problem for getting this information from the NIC. As you may know, the Win32_NetworkAdapter class does not work for MaxSpeed, Speed, and Duplex proporties.
