IT:AD:VNC

Alternative solution to RDP/ – use in a pinch as it uses more bandwidth.

VNC by default uses TCP port 5900+N,[5][6] where N is the display number (usually :0 for a physical display). Several implementations also start a basic HTTP server on port 5800+N to provide a VNC viewer as a Java applet, allowing easy connection through any Java-enabled web browser. Different port assignments can be used as long as both client and server are configured accordingly.
