Remote Desktop Protocol (RDP) is a multi-channel protocol that allows a user to connect to a computer running Microsoft Terminal Services. Clients exist for most versions of Windows (including handheld versions), and other operating systems such as Linux, FreeBSD, Solaris and Mac OS X. The server listens by default on TCP port 3389.^[1] Microsoft refers to the official RDP client software as either Remote Desktop Connection (RDC) or Terminal Services Client (TSC).

Features

• 32-bit color support. 8-, 15-, 16-, and 24-bit color are also supported..
• 128-bit encryption, using the RC4 encryption algorithm (this is the default security; older clients may use encryption of lesser strength). But because of the man-in-the-middle vulnerability in the protocol and Microsoft's implementation, in many circumstances the traffic can be decrypted along the way.^[2]
• Transport Layer Security support.
• Audio allows users to run an audio program on the 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 clipboard can be shared between the remote computer and the local computer.

The following features were introduced with the release of RDP 6.0 in 2006: In cryptography, RC4 (also known as ARC4 or ARCFOUR) is the most widely-used software stream cipher and is used in popular protocols such as Secure Sockets Layer (SSL) (to protect Internet traffic) and WEP (to secure wireless networks). ...

Version history

Based on the ITU T.share protocol (also known as T.128), the first version of RDP (called version 4.0) was introduced with Terminal Services in Windows NT 4.0 Server, Terminal Server Edition. Version 5.0, introduced with Windows 2000 Server, added support for a number of features, including printing to local printers, and aimed to improve network bandwidth usage. Version 5.1, introduced with Windows XP Professional, included support for 24-bit color and sound. Version 5.2, introduced with Windows Server 2003, included support for console mode connections, a session directory, and local resource mapping. The most current version, 6.0, introduced with Windows Vista and Windows Server 2008 includes a significant number of new features,^[4] most notably being able to remotely access a single application instead of the entire desktop, and support for 32-bit color.
