Unable to configure either CredSSP or local PowerShell options. Error: RemoteException: You cannot call a method on a null-valued expression.

Now, the two Hyper-V hosts had been disconnected from the network for quite a while during some network upgrades and were only reconnected to the network this morning, having been disconnected for 56 days.  domain health is fine.  we're using an admin account.  not really sure what the issue is.

Thanks
