undesired automatic modem connexion

Hello,

I am using a small 2-machines network at home (both WIN98SE) , with internet connexion share on one of them.

All went OK till I reinstalled WIN98SE on the “client” machine : since then, automatic connexions occur every time the “gateway” machine is rebooted, and then at regular intervals ( some minutes ).
I have a limited time ISP contract so that’s a problem.
No undesired connexion occurs when the WIN98 “Internet Connexion Share” module is not activated.
This happens even with WIN98SE alone on the “client” machine.

Couldn’t find out how to manage that.

Thanks for your help…
