I really don't care what language this program is created but it needs to work on a home network meaning 1 computer shall tell other computers what to do.
1) Prevents other computers to open websites that you block. must work with Explorer and mozilla firefox
2) Block MSN Messenger
3) Set Timer ( Time setting ) to Lock chosen Network Computer or Lock NOW!
4) This program cannot exit ( end task ) unless you type password to Exit. If password incorrect this program still runs in background.
