Mr.Chamberlain can remote into the CTE computers in the lab now, so I (Deegan) wrote a series of scripts that send a server message when he remotes in. They can be modified to close a program, or pretty much whatever upon an established connection. They probably work, aside from the netstat part taking up a disproportionate amount of time compared to the rest of the commands.

How they work
Upon running funny.bat, it runs a netstat and checks for an established connection from Chamberlains computer, and sends the output to a text file. The contents of the file are then set as variable %connection_status and it checks if the variable is empty. If it's empty, it will call the no_connection.bat script which just restarts funny.bat and kills the original itteration of funny.bat, thus not allowing the script to progress to the final line. If the variable is not empty, the last line will send a server message to the loopback address and the final line will close the script. The last line can be modified to kill a process by changing th command that is run. "Taskkill /F /IM chrome.exe /T" for example would kill chrome upon an active connection.
