If you are encountering a "video remote disconnected" error when trying to connect to your virtual machine (VM) using Remote Desktop in Hyper-V, it may be related to the RemoteFX 3D Video Adapter. This issue can occur if the RemoteFX Windows Firewall rule is not enabled, which is necessary for Remote Desktop connections to function properly after installing the RemoteFX 3D Video Adapter.
To resolve this issue, you can try the following steps:
- Remove the RemoteFX 3D Video Adapter: If you can connect to the VM after removing the adapter, this confirms that the adapter is causing the issue.
- Enable the RemoteFX Windows Firewall rule: Ensure that the firewall rule for RemoteFX is enabled to allow Remote Desktop connections.
- Check the VM's network settings: Make sure that the VM is properly connected to the network and that remote access is enabled.
- Review the Event Log: Look for any error messages related to Remote Desktop in the Windows Event Log, which can provide more details on the issue.
If these steps do not resolve the issue, consider checking for any additional configuration settings or updates that may be required for your specific setup.
