I need some help on how to set this up

I need a program that I can limit the bandwidth of one computer on my home network for example to maximum of 2kps instead of the the full 5kps, my computers are connected by dial-up and ICS host is winxp pro and the one I want to limit is win98se

I also need to instantly kill the network connection from this computer I'm limiting to 2kps, like I push a button in a program and it immediatly kills the network connection to my home network

can anyone help me?

thanks!
