CoRD is a Mac OS X remote desktop client for Microsoft Windows servers using the rdp protocol. It is easy to use, fast, and free for anyone to use or modify.
Usability and Ease of Use
Macs interact well with Windows, and with CoRD the experience is a bit smoother. Great for working on the office terminal server, administrating servers or any other time you'd like your PC to be a bit closer without leaving your Mac. CoRD allows you to view each session in its own window, or save space with all sessions in one window. Scale session windows to whatever size fits you - the screen is resized automatically. Enter full screen mode and feel like you're actually at the computer. The clipboard is automatically synchronized between CoRD and the server effortlessly. CoRD does all this while staying light and quicker than Microsoft's RDC client.
