Scenario:-
Several virtual machine are running on a Hyper-V Machine but then when you try to remote into a VM using Hyper-V Manager or Failover Cluster Manager snap-in but was not able to connect to the VM. The error message that you received was
“Video Remoting Was Disconnected”.
Few things that you’ve try:-
a) Turn off VM and boot up that VM
b) RDP to VM and can access
But each time when try console using Hyper-V Manager snap-in, you will receive “Video Remoting Was Disconnected”. Plan to restart the entire Hyper-V Host, but cannot as i got a lot of Production virtual machine which is running.
Solution:-
Therefore this is one of the trick that i have tried
1. Go to physical NIC and disable
a) TCP Connection Offload (Ipv4 /ipv6)
b) TCP/UDP Checksum Offload (Ipv4 / ipv6)
Then i try again and was able to connect to the VM without any problem. So give it a try and this solution probably will fix your issue.
