What Is RDP? How To Get Free RDP And How To Use it free New Update 2016

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

History

Every version of Microsoft Windows from Windows XP onwards^[4] includes an installed Remote Desktop Connection (RDC) ("Terminal Services") client (mstsc.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, 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.^{[citation needed]}

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]}

Features

• 32-bit color support. 8-, 15-, 16-, and 24-bit color are also supported.
• 128-bit encryption, using the RC4 encryption algorithm, as of Version 6.^[31]
• Audio Redirection allows users to process audio on a remote desktop and have the sound redirected to their local computer.
• File System Redirection allows users to use their local files on a remote desktop within the terminal session.
• Printer Redirection allows users to use their local printer within the terminal session as they would with a locally- or network-shared printer.
• Port Redirection allows applications running within the terminal session to access local serial and parallel ports directly.
• The remote computer and the local computer can share the clipboard.

Microsoft introduced the following features with the release of RDP 6.0 in 2006:

• Seamless Windows: remote applications can run on a client machine that is served by a Remote Desktop connection. It is available since RDP 6.^[32]
• Remote Programs: application publishing with client-side file-type associations.
• Terminal Services Gateway: enables the ability to use a front-end IIS server to accept connections (over port 443) for back-end Terminal Services servers via an https connection, similar to how RPC over https allows Outlook clients to connect to a back-end Exchange 2003 server. Requires Windows Server 2008.
• Network Level Authentication
• Support for remoting the Aero Glass Theme (or Composed Desktop), including ClearType font-smoothing technology.
• Support for remoting Windows Presentation Foundation applications: compatible clients that have .net framework 3.0 support can display full Windows Presentation Foundation effects on a local machine.
• Rewrite of device redirection to be more general-purpose, allowing a greater variety of devices to be accessed.
• Fully configurable and scriptable via Windows Management Instrumentation.
• Improved bandwidth tuning for RDP clients.^{[citation needed]}
• Support for Transport Layer Security (TLS) 1.0 on both server and client ends (can be negotiated if both parties agree, but not mandatory in a default configuration of any version of Windows).
• Multiple monitor support for allowing one session to use multiple monitors on the client (disables desktop composition)

Release 7.1 of RDP in 2010 introduced the following feature:

• RemoteFX: RemoteFX provides virtualized GPU support and host-side encoding; it ships as part of Windows Server 2008 R2 SP1.

Security issues

Version 5.2 of the RDP protocol in its default configuration is vulnerable to a man-in-the-middle attack. Administrators can enable transport layer encryption to mitigate this risk.^[33][34]

RDP sessions are also susceptible to in-memory credential harvesting, which can be used to launch pass the hashattacks.^{[citation needed]}

In March 2012, Microsoft released an update for a critical security vulnerability in the RDP protocol. The vulnerability allowed a Windows computer to be compromised by unauthenticated clients and computer worms.^[35]

RDP client version 6.1 can be used to reveal the names and pictures of all users on the RDP Server (no matter which Windows version) in order to pick one, if no username is specified for the RDP connection.
