We are running a 2012 Hyper-V cluster managed primarily by SCVMM 2012 R2 and as a backup Failover Cluster Manager.

I have installed Windows 10 RSAT (WindowsTH-KB2693643-x64.msu) and been testing I can again manage our various services with my Windows 10 client.

When trying to connect to either of our 2012 Hyper-V cluster I get the following:

Connection Not Supported

Cluster XXXXXXX not supported

The cluster to which you are attempting to connect is not a version of the cluster supported by this version of Failover Cluster Manager

On each host Failover Cluster Manager connects without issue.

I have traced the connections, checked firewalls, checked WMI and RPC etc and cannot find an issue.

My colleagues can connect with v6 of Failover Cluster Manager.

If I try connect without appropriate credentials I does fail for not enough privileges so I can see it does talk to the cluster.

Any thoughts? Next step? Bug?  

I'm highly interested in an answer here too.  Just installed the much needed RSAT for win10, but can't manage my 2012 H-V cluster...
