How to remotely lock a computer?

Question

webpack

Good afternoon. The task is this: It is necessary to block the child's computer (Windows), so that he sometimes stops playing DotA and starts studying. Is there any software that allows you to do this not on a schedule, but remotely, from another computer or smartphone?

Answer 1

We begin the massacre with these kids, who wins who wins!
First, we set up a router for remote control (port 80 out)
of course with a dynamic address, you will have to have some kind of DDNS thread (whatever the router pulls)
Second (if the router supports) we limit the speed to the client, let him suffer, watch the slide show.
if it doesn’t help, we chop it off completely (well, why did the darling jump? ha ha), what hasn’t been turned off yet, we continue the conversation .. first install it in autorun, something like netcat and continue to unscrew the knobs (figuratively, the settings knobs), first start it in the background many different applications so that they eat more resources (ha ha the reprisal is close) do the brakes stop?
shutdown

If you don't bother. Set a password for the account. Do not disclose password.
Install TeamViewer. Remotely through TeamViewer enter the password from the account when necessary. Remotely turn off the computer also through TeamViewer. Works with PC and phone.
And for the cool guys - use the local policies of Windows and SRP
