Remote
                      Administration Tool  is
                      a small free remote control
                      software package derived
                      from the popular TightVNC  software.
                      With "Remote
                      Administration Tool", you can see the desktop
                      of a remote machine and control it  with your
                      local mouse and keyboard, just like you would do it sitting
                      in the front of that computer. Small, easy, no installation
                      required.
