microsoft windows default Remote Desktop Services is best in my opinion because of its default installed in windows you don't need to install in every PC where you want to connect. Remote Desktop is one of the best remote access utilities available, not because it is built into Windows, but because of all the extras, it includes. First and foremost is its ability to print remotely. Other than Gbridge (when using the Remote Desktop client), no other free remote access tool allows printing from the host to the remote client and Microsoft has also made available a downloadable version of Remote Desktop for versions of Windows all the way back to Windows 95 and NT 4.0. Host PCs must be Windows 2000 (via Terminal Services)

What I like the best is surely the speed. The connection is very fast (no lagging when moving the mouse). In addition to that we have full control (For example: virtual keyboard, mouse, and standard keyboard operation like windows, ESC, CTRL+ALT+DEL and all of the function keys) I was also able to access system resources as you are right in front of the computer, (For Example, shutting down and restarting the stations)

The remote desktop is a software especially to connect to remote servers and run other applications. It is easy to use as you are basically connected to another desktop and you're able to control it
