Hyper V Server has no network connection after upgrade from 2012 to 2019
I upgraded a server that lives on a 2019 Hyper-V. I upgraded from 2012 to 2019. The server now has a Bang over the network connection. I disabled the adapter and enabled the adapter, I changed from dhcp to static and still nothing. I created a new virtual switch but and connected to that but it did not help.
When I attempt to ping the gateway I get the error
PING: Transmit Failed General Failure

is there an updated nic driver that needs to be installed?
ASKER
there is one Item under Network adapters that has a Bang. WAN Miniport (IP). Is this my issue. Which drivers do I use for this?
Hello,
Select the driver that is with the warning, right click and then update driver, once update the driver, validate if the vm has the same problem with the gateway.
Additional validates that you have enabled the services integrated in the vm.
Wan Miniport is a driver that allows the connection of alternative methods in Windows, such as Point-to-Point Protocols over Ethernet (PPPoE) and wireless WAN networks.

At the level of virtual adapter, do you have any advanced features enabled at the adapter level in hyper-v ?. Check the vm configuration on the virtual hardware

I reinstalled the driver for the WAN Miniport(IP). The Bang went away but still no connection. I opened an elevated command prompt and ran
netsh winsock reset. Still, after the restart, there is still no network connection.
