When I try to create a virtual switch from WAC and select external, it tries to load available network interfaces but it always fails with

"Couldn't load the network adapters. Error: (1) RemoteException: No MSFT_NetIPInterface objects found with property 'InterfaceIndex' equal to '9'. Verify the value of the property and retry. (2) RemoteException: No MSFT_NetIPInterface objects found with property 'InterfaceIndex' equal to '6'. Verify the value of the property and retry. (3) RemoteException: No MSFT_NetIPInterface objects found with property 'InterfaceIndex' equal to '5'. Verify the value of the property and retry. (4) RemoteException: No MSFT_NetIPInterface objects found with property 'InterfaceIndex' equal to '4'. Verify the value of the property and retry."

I am running the latest hyper v server.

    Hi，

    Have you updated the NIC driver?

    Please try to use the following method to see the result:

    Remove Hyper-V role
    Open an elevated command prompt and run: netcfg -d (make sure you have console access as this will kill all network connections)
    Reboot
    Add Hyper-V role
    Create your vSwitch.

    Best Regards,
    Daniel
