BLock a computer on the network

Solution
You can probably accomplish that most easily by a router configuration change. Do you want to block all network access, Internet access, or specific times/sites?

Wired or wireless connection?

What brand and model router do you use?

You can control the wireless network by changing your wireless password by changing it in the router: http://www.tomshardware.com/forum/38111-43-find-change-wireless-security

Once you change the password then only give it to those that you want on the network.

Many routers have QOS (quality of service) settings that you can set to limit the speed or times that specific users can connect. Check your router manual to see if you have this feature.
