I have a 3 node Hyper-V Cluster on Server 2012 r2 platform. Has been running great no issues. Today, I went to manage a VM and the MMC says the service is not running. I confirmed that it is running and even restarted the service. I then tried to get into the Failover Cluster MMC and it cannot connect to the cluster. I tried this on all three nodes plus on my local machine and nothing works. Another odd thing I noticed is the server said there were updates to be installed - went to the updates section and it said the update service was not running (which it was).
Any ideas what's going on? I'm afraid to reboot any of the servers in fear something isn't going to come back on right.
