Network adapter configuration error after quick migrate of stopped VM in 2012 r2 data-center edition 3 node cluster environment

Question

We've got a couple of Windows 2012 r2 / Hyper-V 3 node clusters, and I have a problem with network adapters on them.
 I have 3 node cluster all vm running fine on node 1 and 2 also quick and live migration very good between
node 1 and node 2, but no vm migrating on node 3.  show "Network adapter configuration error".
If the VM is powered off, and I move it to 3rd
host (quick migration via Failover Cluster Manager), the network adapter loses its connection to the virtual switch - it turns to "Configuration Error"..if
manually change V switch of every VM then it worked only on 3rd node, and having same problem on node 1 and 2. 
Quick migrate with the power off, and it fails to pick up the VSwitch on the3rd host.
Thanks

Hi,
> I created a new VM via the Failover Cluster Manager (ie not via Hyper-V manager on one of the nodes).
Generally, this issue happens if a network adapter is added or removed on a highly available virtual machine using the Hyper-V manager console. Since the Hyper-V Manager console is not cluster aware, which means that configuration changes that are made to
virtual networks or virtual machines in the Hyper-V Manager console must be replicated to the other cluster nodes by using the “refresh virtual machine configuration” option in the Failover Cluster Manager console.
I know that “refresh virtual machine configuration” option is not needed if you change virtual machine settings using the Failover Cluster Manager console, but you may try to refresh the configuration of virtual machine to check the result.
In the Failover Cluster Manager console, expand Services and Applications, and then click the virtual machine for which you want to refresh the configuration.
In the Actions pane, scroll down, click More Actions and then click Refresh virtual machine configuration.
