How do you get a list of only physical adapters?

Summary

How do you obtain a list of only the physical adapters on Windows?

Question

I am trying to obtain a list of only the physical adapters and also a separate list of the virtual adapters on Windows. I am first setting LM_A_PHYSICAL_ETHERNETID to (LM_A_VAL_TYPE)0 to obtain the list of physical and virtual adapters and then setting it to (LM_A_VAL_TYPE)1 to obtain only the physical adapters. I am then comparing the two lists and extracting the virtual adapters.

After setting LM_A_PHYSICAL_ETHERNETID to (LM_A_VAL_TYPE)0 calling lc_hostid() returns all adapters as expected. However, if you then set it to LM_A_VAL_TYPE)1, calling lc_hostid() still returns all adapters.

So how exactly can you obtain a list of only physical adapters?

Answer

Here's an example of using a WMI utility to determine which adapters are physical. That can also be done as scripted calls from something like Powershell.

Run the wmic application
c:> wmic
wmic:root\cli>

at the wmic prompt type "NIC" to display all details on all NICs on the system.

To get a subset of NIC details, and to determine what is reported as physical, enabled, and what their driver name is, type the following at the wmic prompt:

wmic:root\cli>path win32_networkadapter get description, physicaladapter, pnpdeviceid, macaddress, netenabled
