Hyper-V

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

Hyper-V 2016 Trouble...  
HVMMC errorPSSession errorI have two 2012 r2 VM DCs running on a standalone Hyper-V 2016 host.  I set up remote management VIA PowerShell and Hyper-V Management console. I guess over WINRM with CredSSP.  Well everything was working fine (6-8 months or so now).  I all stopped a few weeks ago. I tried to pin it down to a security update but could not.  When I try to start a new PSSession or authenticate on the HVMMC I get an HTTP error code 403.  Everything I have found so far seems to be related to exchange and IIS,  neither of which are on these VM and the host is just Hyper-V it can't run anything else.  Also at the same time I could no longer check point my VM's which is required to work for my Unitrends recovery appliance.  It's like the entire management subsystem is broken.   I am still able to RDP into the host and manage the VMs with PowerShell but that's it...  I looked through application and error logs.  But I didn't see anything that appeared relevant to me...
