Controlling Another Computer in One Network

A little story of my profession as an IT teacher in elementary school. when the hour of rest as usual the kids drove to the lab computer (for nge-game). According to school rules, a computer lab may not be used for nge-game during recess. But since anak2nya bandel2, dicuwekin rules only. But I do not run out of ideas to overcome the stubborn anak2, ie by Radmin installed on each computer with the goal, every child who nge-game in the computer lab, not just close the game through my laptop (I also happen to computers connected to the network.
Here are the steps for setting up Radmin.
1. Radmin software should be available, the reply has not done, can ask a neighbor or donlud here (radmin33int.zip).
2. After the software downloaded, then install Radmin is to control (controller) on a computer that we use (the name rview33.exe). Then create a new user and do not forget the password.
3. After that, who wants to move kekomputer controlled (another computer) and install Radmin for the client (name rserv33.exe). Radmin installed the same as the first, which is to enter a user and password. That will be used when we want to control the client computer (must enter a username and password).
4. Back kekomputer us, and run Radmin Viewernya.
To run it, we must know the IP address of the computer that we want to control.
Good luck ...
