Hi , i use my pc to share connection with another pc.This pc with Vista and another With XP(SP3). I installed Windows seven and made the same wich i did in Vista to share my internet connection, but the internet does not work on XP. What im doing(Vista[wich works] , and Seven[Wich does not working] : > In the USB modem connection > properties >Sharing > Allow other network.... > In Ethernet network i configured manual IP adress In XP(SP3) > Set up A ip adress, and a Gateway ( The server IP ) , and my ISP DNS . Well done... It's work with vista , but not with Seven... What's wrong with these steps with Seven? what to do to work? Thank you.
