Ok, so I found this on the Internet and tried it. This allowed HyperV Manager on HyperV-0 to connect back to the ReplicaV-0 Host<br><br>Open "<em>Window Security</em>"<ol><li>Open "<em>App &amp; Browser control</em>"</li><li>Click "<em>Exploit protection settings</em>" at the bottom</li><li>Switch to "<em>Program settings</em>" tab</li><li>Locate "<em>C:\WINDOWS\System32\vmcompute.exe</em>" in the list and expand it</li><li>Click "<em>Edit</em>"</li><li>Scroll down to "<em>Code flow guard (CFG)</em>" and <strong>uncheck</strong> "<em>Override system settings</em>"</li><li>Start vmcompute from powershell as administrator&nbsp;net start vmcompute</li><li>Restart</li></ol>Start Hyper-V Manager as administrator<br><br>I am now trying to replicate the server back accross. We will see if it fails.&nbsp;

Hello,<br><br>Validate on the destination server that all the services associated with Hyper-v are running without problems. Validate the WS-Management service.<br><br>Additionally, it validates the event viewer associated with the hypervisor, it can give you the IDs of the events and a description of the possible problem.<br><br>Reboot your destination host, and validate the replica's behavior.<br><br>stay tuned.<br><br>Regards.

I am having problems with HyperV replication Server 2019 HyperV

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.
