Shree Ganesha


Dear Friends,

Pls tell me what shd I be doing in order to block registered users of
any ISP from routing INTERNET Connection through a windows client.

Many of ISP user pay only for one internet connection and the route
the internet connection to other computers.

I am here to write a program a small module to be installed on the
client computer that will disallow the following

1.) Internet Sharing (ISHARE)
2.) The use of any kind of proxy servers on the client machine

Soln I think can solve my problem...

1.) I will register the mac address of the lancard along with my
clients database and then disallow the presence of any other lan card
on the same machine.

Problem: The client will not be able to use file sharing and printer
sharing due to these kind of restrictions.

Kindly suggest a walk around.....

2.) I will check the ports open for the other lan cards and block them
during the session for which my lancard is running

Pls tell me the probable solns

Pls also discuss the probable problms

Best Regards
Ganesh J. Acharya
