My 2012 R2 cluster (joined to domain) was running just fine until this morning. I am not able to connect remotely or locally to failover cluster manager OR the hyper-v manager on my node HV01 (I can connect to hyper-v manager to HV02).
Everything on the server seems to be running fine though. The only logs I see are in Microsoft/Windows/WMI-Activity:
