Even though I have made no changes to my environment, other than normal OS patches, I unable to move my vm's between host servers. This is true for host server that are part of a cluster and those that are not. When I attempt to do this inside of VMM, I get a error message stating that "CLR is not terminating". Research I am finding points to .Net Framework 4.5 not being installed. I have not found any more recent for Windows Server 2016 and this error. Other article talk about different circumstances when the problem occurs. I only see this attempt to move VM's between hosts. Also when using Hyper-V Manager and attempting to move between hosts I receive: "Virtual machine migration operation failed at migration source. Failed to establish a connection with host: '*': no credentials are available in the security package. The Virtual Machine Management Service failed to authenticate the connection for a Virtual Machine migration at the source host." For all my hosts authentication is configured to use Kerberos and NOT CredSSP.
Please keep in mind, this was working as configured for most of this year. I have not changed the RunAs account in VMM for this operation, it is enabled, active, and there are no problems with the password.
Any help helping to location more information about this problem or how to resolve would be greatly appreciated.
