However, when NLA is enabled, and if you’re on domain connected system, you may receive this error message which prevents RD connection:

The remote computer that you are trying to connect to requires Network Level Authentication (NLA), but your Windows domain controller cannot be contacted to perform NLA. If you are an administrator on the remote computer, you can disable NLA by using the options on the Remote tab of the System Properties dialog box.
