Message "Unknown WMI error" appears if performing a Hyper-V export to a node with a stopped Cluster Service (4039722)

When performing a virtual export to a Windows 2012 R2 CSV, the following error message is displayed when attempting to connect to the Hyper-V host:

"Unknown WMI error: There are no more endpoints available from the endpoint mapper.

WMI query: SELECT * FROM MSCluster_Cluster -namespace root\MSCluster"

The error message is incorrect.  It should state a message along the lines of, "Export to 'IP/Host Name' is not possible due to the cluster service being stopped."

WORKAROUND:

Start the cluster service or perform a cluster destroy (only do this if the cluster is not functioning as cluster anymore).
