This happened the same time Windows moved from Terminal Services to Remote Desktop Services.<\/p>\n<p>What&#8217;s the difference? When connecting to a Terminal Server, a user starts a session and types in their credentials. When using an RD Session Host server, a user typically enters credentials into a client-side dialog box.\u00a0NLA forces the client computer to present user credentials for authentication before the server will create a session for that user.<\/p>\n<p>Because of that process, it\u2019s sometimes called \u201cfront authentication.\u201d Servers that are running Windows Server 2008\/Vista or later, and clients running Windows XP SP3 or later, support NLA. Because NLA relies on a technology called Credential Security Support Provider [CredSSP] Protocol, if you\u2019re using a Remote Desktop Protocol [RDP] client for another OS, you\u2019ll need a client that supports NLA.<\/p>\n<p>Microsoft Remote Desktop Connection Client for Mac doesn&#8217;t.<\/p>\n<p>Fortunately there is an alternative that does. Via the AppStore, search for &#8216;Microsoft Remote Desktop&#8217; &#8211; Version 8.0.36 (Build 27228) is what I have today. Install this, try and connect to your Windows machine (Win10 for me) and you are in business.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>So, I had occasion to try and connect to a windows machine from my Mac.
