Identify non-physical ethernet adapter

[C# Programming]

Hi Gurus,

I need to identify if a network interface card (specifically ethernet) is physical or non-physical?

I use the "NetworkInterface" class to enumerate the network cards. However, in my system there is one LAN adapter that is present and is not physical. This doesnt show up as a virtual adapter also.

Is there any API in .NET which can help to identify if a device is actually present in the machine or not???


Thanks in advance.
