Hyper-V Server 2019 VmSwitch no longer operational Event ID 22,24, 16949, 16950, 27, 32

Hello!

I got similar problems as mentioned in this post:

I couldn't solve it my own with driver updates & windows updates. I upgraded the physical Network Drivers Intel I210 Gigabit Network Connection.
But my Microsoft Network Adapter and Hyper-V Virtual Ethernet Adapter remain outdated:

Hi,

After researching, I also find another post mentioning the similar issue as yours.

If driver updates & windows updates could not resolve your issue, have you also checked if NIC firmware is update to date?

Also, the post suggested that you could delete the virtual switches and the NIC team, and then rebuild the networking.

For your reference:
