Remote Desktop Connection Manager is a essential tool if you run a lot of virtual machines or need to connect to a lot of customers as i do. One of the new features in version 2.7 allows the ability to connect directly to virtual machines (called virtual machine connect-to-console support). Configuring a connection for this new feature is rather easy once you have the ID of the virtual machine.

The following PowerShell command should do the trick:

        get-vm | Select Name,ID

Once you have this information, enter it on the Server Settings tab like in the following screen shot, i’ve used the Win10 VM:

Once you have this set up, you should be almost set to go…We also need to set some registry settings otherwise you will be facing this error:

The reason for the error appears to be that the Credential Security Service Provider (CredSSP) policy on the Hyper-V host is not enabled to authenticate user credentials from a remote location.
