Question

I get following error while creating any type(external, internal and private) of virtual switch on Hyper-V using Hyper-V manager.

Failed to create virtual ethernet switch.

The system cannot find the file specified. (0x80070002)

Here is a to screenshot of error:

Getting the same error when trying to create from Powershell.

Solution

1. Go to Settings -> Network & Internet

2. Select Change adapter options

3. Right click on NIC Adapter -> Properties

4. Check if the Hyper-V Extensible Virtual Switch is installed in your NIC's Properties

   • If it is installed, uninstall it.

   5.1 Select Install

   5.2 Select Protocol

   5.3 Select Hyper-V Extensible Virtual Switch

6. Create the virtual switch on Hyper-V using the Hyper-V manager

Instant fix on my 180 Eval Datacenter 2019. I added Hyper-V but couldn't select a network adapter. Did this, and it worked. If your NetAdapterName is "Ethernet 2" you can just add "quotes" around it in the given command. Thanks!

I had my wifi adapter already sharing, had to disable it first
