Symptoms

The error pops-up when trying to create a VSS-Aware set for Microsoft Cluster Hyper-V, after providing the network credentials.
"The object invoked has disconnected from its clients"

Cause

The DS-Client computer is not member of a domain and is located in a different subnet than the Hyper-V machines, as a result the IPs and names of the cluster nodes need to be added into hosts file (on the DS-Client computer), by mistake the IPs and names of the nodes were paired incorrectly (the IP of the first node was linked with the name of the second node and viceversa for the second node).

Workaround

Ensure that the IPs and names of the cluster nodes and virtual cluster node are correctly added in the hosts file on the DS-Client computer.
