Can't list network adapters when creating an external virtual switch from Windows Admin Center

Question

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.

Daniel
