The connection cannot proceed because authentication is not enabled

The connection cannot proceed because authentication is not enabled

I added a shortcut for a Hyper-V Console session.

When I try to connect I get an error "The connection cannot proceed because authentication is not enabled and the remote computer requires authentication be enabled to connect".


But when I click OK it connects anyway.

On that server in System Properties > Remote > Remote Desktop the option "Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)" is UNCHECKED.

Host is running Windows Server 2016 Standard

If I check that option under Remote Desktop and then try to connect again, it works with no error.

I'll keep that option checked (I had unchecked it due to a remote desktop issue resulting from a windows update a few months ago), but I am just curious why RDM gives an error telling me 'the remote computer requires authentication' when the option is actually unchecked on the server.

Hello,

RDM use a Microsoft ActiveX to establish RDP connection in embedded mode. In fact, it's the same ActiveX that Microsoft use in RDC Manager.
As per your first screenshot, I suspect that the error is coming from this ActiveX.

That being said, do you encounter the same error using RDC Manager from Microsoft?

I've never used RDCMan from Microsoft and I forgot ActiveX was still a thing ;-) I enabled the "Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)" option and that resolved the issue for me. Thanks for the quick reply.
