The remote computer requires Network Level Authentication.
Another sort of reminder post for me but when you get this error message when trying to RDP to an NLA enabled Windows Server 2008 server or Windows 7 workstation, just follow the steps in the following Microsoft Knowledgebase article.

This enables CredSSP and can be used on Windows XP Professional SP3.

What if the allow any version of RD is selected but it still doesn’t work?
Hi Juan, I’d say double-check that the user you’re attempting to authenticate as has permissions to use remote desktop and that the proper firewall entries are configured to permit traffic on TCP/3389
This worked for me Thanks
