We have Windows Server 2012 R2 that has 2 Virtual Machines inside running Win 7 Pro sp1. They were working fine until last week when I opened Hyper-V manager, there was no VM listed. Tried to connect to them by right clicking on Hyper-V manager --> connect to server but I get an error message : "An error occurred while attempting to connect to server "servername". Check that the Virtual Machine Management Service is running and that you are authorized to connect to the server". So I checked the services and found that VMMS doesn't start.
so far I have tried disabling Firewall, made an exception on Anti-Virus, Restarted Windows Management Instrumentation and none of them made any changes.
Do you guys have any ideas how to resolve this issue?
