System setup.
Hyper-V installed on a Windows 2008 R2 SP1 Datacenter System with the latest patches applied. System has 512GB of RAM and 40 cores available.
The system had been working fine until I had issues rebooting the Hyper-V host server after applying Sep 2016's MS monthly patches. I do have 3 other machines where these patches were applied and they do not have the issue.
When I highlight the local VM from within the Hyper-V Management interface I can see the status of the VM just fine. However when I attempt to connect to the local VM and open up a 'Console' session I get the following error:
"Cannot connect to the virtual machine. Try to connect again. If the problem persists, contact your system administrator. Would you like to try connecting again?"
If I try again I end back up to the same screen. I have tried restarting the Hyper-V services, removing and reconnecting to the local server via the management console, doing a shutdown then starting the Hyper-V host and the problem still remains. I checked the Hyper-V logs on the Hyper-V host and the only error I saw listed in the events follows:
