I am using the below JAVA code to capture the desktop of a remote machine
Robot robot = new Robot();
BufferedImage screenShot = robot.createScreenCap
A simpler alternative to the above answers to to transmute the terminal session (RDP) into the console session. The session will then display to the physical screen (Switching the user of anyone currently logged into the physical machine). The following command does this:
for /f "skip=1 tokens=3" %%s in ('query user %USERNAME%') do (tscon.exe %%s /dest:console)
