I'm trying to remote onto a Windows 2012 Server using Remote Desktop Connection for Mac. Using the same credentials, it works from my Windows PC (using Remote Desktop for Windows), but trying to do it from my Mac I get the error:

That's the ticket... if you check your version of remote desktop for mac it says it's up to date... you have to know that the new version of RDP for mac is called Microsoft Remote Desktop.... maddening!!

I doubt this a 'problem' with the mac as such nor does it have anything to do with Remote Desktop for Mac which is an entirely different product and for which this forum is for. Questions about RDC for Mac should be put on the relevant Microsoft forum rather than here. However your problem may be with your understanding of the secure remote connections requirements between your server and remote connections. I doubt you'd be aware of any of this as generally server administrators won't necessarily discuss them. By default a mac will not have server-client trust certificates installed simply because the exchange won't happen transparently between an MS based server and non MS-OS such as OS X.

You begin to solve the problem by asking your server administrator for the server's root certificate. He/she has to export this using the built-in tools. They should know how to do this? Once exported save it to a memory stick, insert it into your mac, double click on the .cer file and when prompted install it as a system keychain. On further prompts make sure you select 'Always Trust'. Launch RDC for Mac and you should be OK?

Thanks jaredfs. Im running Mac OS X Yosemite and just upgraded to Win10. I used to use the Remote Desktop Connection App but after the upgrade to Win10, I couldnt connect from my Mac. I installed Microsoft Remote Desktop and now I can connect to my Win 10 machine with no issues. Thanks for the quick fix!

So i HAVE been using CORD to log into my PCs from OSX. But it was not working on the Win10 box. I was in the insiders Beta program. and after some update CORD finaly started working. Well as said above, that was short lived with the next update CORD stopped working again. I can remote desktop in from a PC but not from CORD on my Mac.

So following the advice above i downloaded MICROSOFTS's remote desktop. and as soon as i tried to remote into my Win10 box, a message come up about generating a security certificate for this user. I said Yes, and boom! remote desktop ed in perfectly!

Sadly CORD (my preferred client) is still NOT working, but now we know WHY! Win 10 looks for this "security certificate" and if it doesnt find it Win10 will REFUSE the connection. This must be a PC to PC handshake that we never see.

Again the only lead I have is that Microsoft Remote Desktop app works on the original box, but not CORD. And i THINK this is due to a security certificate issue. Problem is I have not idea where to find that in Windows 10

Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft Corporation which provides a user with a graphical interface to connect to another computer over a network connection.[1] The user employs RDP client software for this purpose, while the other computer must run RDP server software.

Several clients exist for most versions of Microsoft Windows (including Windows Mobile but the support has ended), Linux (for example Remmina), Unix, macOS, iOS, Android, and other operating systems. RDP servers are built into the server and professional editions of Windows operating systems but not home editions; an RDP server for Unix and OS X also exists (for example xrdp). By default, the server listens on TCP port 3389[2] and UDP port 3389.[3]

Every server and professional version of Microsoft Windows from Windows XP onward[5] includes an installed Remote Desktop Connection (RDC) ("Terminal Services") client (.mw-parser-output .monospacedfont-family:monospace,monospacemstsc.exe) whose version is determined by that of the operating system or by the last applied Windows Service Pack. The Terminal Services server is supported as an official feature on Windows NT 4.0 Terminal Server Edition, released in 1998, Windows 2000 Server, all editions of Windows XP except Windows XP Home Edition, Windows Server 2003, Windows Home Server, on Windows Fundamentals for Legacy PCs, in Windows Vista Ultimate, Enterprise and Business editions, Windows Server 2008 and Windows Server 2008 R2 and on Windows 7 Professional and above. The home versions of Windows do not support RDP.

Microsoft provides the client required for connecting to newer RDP versions for downlevel operating systems. Since the server improvements are not available downlevel, the features introduced with each newer RDP version only work on downlevel operating systems when connecting to a higher version RDP server from these older operating systems, and not when using the RDP server in the older operating system.[clarification needed]

Based on the ITU-T T.128 application sharing protocol (during draft also known as "T.share") from the T.120 recommendation series, the first version of RDP (named version 4.0) was introduced by Microsoft with "Terminal Services", as a part of their product Windows NT 4.0 Server, Terminal Server Edition.[1] The Terminal Services Edition of NT 4.0 relied on Citrix's MultiWin technology, previously provided as a part of Citrix WinFrame atop Windows NT 3.51, in order to support multiple users and login sessions simultaneously. Microsoft required Citrix to license their MultiWin technology to Microsoft in order to be allowed to continue offering their own terminal-services product, then named Citrix MetaFrame, atop Windows NT 4.0. The Citrix-provided DLLs included in Windows NT 4.0 Terminal Services Edition still carry a Citrix copyright rather than a Microsoft copyright. Later versions of Windows integrated the necessary support directly. The T.128 application sharing technology was acquired by Microsoft from UK software developer Data Connection Limited.[6]

This version was introduced with Windows XP Professional and included support for 24-bit color and sound. It is supported on Windows 2000, Windows 9x, and Windows NT 4.0.[7] With this version, the name of the client was changed from Terminal Services Client to Remote Desktop Connection; the heritage remains to this day, however, as the underlying executable is still named mstsc.exe.

This version was introduced with Windows Server 2003, included support for console mode connections, a session directory, and local resource mapping. It also introduces Transport Layer Security (TLS) 1.0 for server authentication, and to encrypt terminal server communications.[8] This version is built into Windows XP Professional x64 Edition and Windows Server 2003 x64 & x86 Editions, and also available for Windows XP as a download.

This version was introduced with Windows Vista and incorporated support for Windows Presentation Foundation applications, Network Level Authentication, multi-monitor spanning and large desktop support, and TLS 1.0 connections.[9] The RDP 6.0 client is available on Windows XP SP2, Windows Server 2003 SP1/SP2 (x86 and x64 editions) and Windows XP Professional x64 Edition through KB925876. Microsoft Remote Desktop Connection Client for Macintosh OS X is also available with support for Intel and PowerPC Mac OS versions 10.4.9 and greater.

This version was released in February 2008 and is first included with Windows Server 2008 and Windows Vista with Service Pack 1 and later backported to Windows XP with Service Pack 3. The RDP 6.1 client is available on Windows XP SP2, Windows Server 2003 SP1/SP2 (x86 and x64 editions) and Windows XP Professional x64 Edition through KB952155.[10] In addition to changes related to how a remote administrator connects to the "console",[11] this version has new functionality introduced in Windows Server 2008, such as connecting remotely to individual programs and a new client-side printer redirection system that makes the client's print capabilities available to applications running on the server, without having to install print drivers on the server[12][13] also on the other hand, remote administrator can freely install, add/remove any software or setting at the client's end. However, to start a remote administration session, one must be a member of the Administrators group on the server to which one is trying to get connected.[14]

This version was released to manufacturing in July 2009 and is included with Windows Server 2008 R2, as well as with Windows 7.[15] With this release, also changed from Terminal Services to Remote Desktop Services. This version has new functions such as Windows Media Player redirection, bidirectional audio, multi-monitor support, Aero glass support, enhanced bitmap acceleration, Easy Print redirection,[16] Language Bar docking. The RDP 7.0 client is available on Windows XP SP3 and Windows Vista SP1/SP2 through KB969084,[17] and is not officially supported on Windows Server 2003 x86 and Windows Server 2003 / Windows XP Professional x64 editions. It is also not officially supported on Windows Server 2008.

Most RDP 7.0 features like Aero glass remote use, bidirectional audio, Windows Media Player redirection, multiple monitor support and Remote Desktop Easy Print are only available in Windows 7 Enterprise or Ultimate editions.[18][19]

This version was released in Windows 8 and Windows Server 2012. This version has new functions such as Adaptive Graphics (progressive rendering and related techniques), automatic selection of TCP or UDP as transport protocol, multi touch support, DirectX 11 support for vGPU, USB redirection supported independently of vGPU support, etc.[20][21] A "connection quality" button is displayed in the RDP client connection bar for RDP 8.0 connections; clicking on it provides further information about connection, including whether UDP is in use or not.[22]
