This is rare. Since this case requires deeper investigation and log analysis is not with the forum scope, I would suggest that you contact Microsoft Customer Support and Services where more in-depth investigation can be done so that you would get a more satisfying explanation and solution to this issue.

Hi,
It seems that the adaptor is not connected with any virtual switch.

YuhanDeng-MSFT thankyou for your reply

TP2 Hyper-V Network adapter is configured to the same virtual switch as TP1

I have deleted this and recreated a new virtual switch and pointed both servers to it.

TP1 gets a network connection but TP2 fails

I have tried to add a second virtual adapter but this also gets the same problem.

Just installed two hyper-V servers from a backups

This might be problematic. What is the history here? Do you meant the host was restored from backup? Does the host hardware support the operating system installed?

Yes I have restored both backups onto the Hyper-V server. both backups and Hyper-V server are server 2016. one works fine the other one boots and runs fine but with the above network error. I have removed the Hyper-V instance and re set it up still the same. both servers are installed the same way.

Still not quite clear. Did your restore the host? Better option would be to clean install the host, patch fully, add hyper-v role, and import the guests. Does the host hardware support the operating system installed?
