How to Adminster Other Wireless Computers

Hello,

Can someone tell me how to setup or control other wireless computers from main wireless computer. i have three wireless laptops but I want to setup or customise the other two wireless web browsing, time limits, web contents, etc. Is there a way to setup so that all other user's can be viewed or controlled. Please remember this is not to be used outside but for a family. Your help will be kindly appreciated.
