VNC Free Edition

This excellent program lets you assume control of another computer across a local network or the Internet. A particularly good choice for mobile users, VNC includes a Java client that enables you to access a remote computer via any browser without installing any software.
At present, there are ready-made versions for Windows, Unix, Linux, and Solaris. In our testing, VNC performed without considerable slowdown over a LAN connection and did not consume much memory. (To operate over a slow connection, you may need to reduce colors, remove the desktop wallpaper, or have only one active window.)
Version 4.1.2 includes unspecified updates.Download Here
