HI..
I would like to know how to connect (FOR INTERNET) using a PC-PC cross cable

1. A laptop and a desktop.
2. Laptop(Dell) running Vista Home Basic.
3. Desktop running XP Professional SP2.
4. Laptop accesses Internet using Netgear wi-fi router.

I have connected a PC to PC cable between laptop and desktop.

I WANT TO ACCESS INTERNET IN THE DESKTOP.

I have already connected the desktop and file sharing is working fine.
Somebody please help me how to enable internet in the desktop.

I have attached the screenshot of the ip configs of laptop AFTER connecting the PC to PC cable . hope that helps.
Looking forward to your replies.
Thank You.

After you enable ICS, the desktop should get a private IP from the laptop.  The laptop turns into a router and dhcp server if you will.  Do you have Internet on your desktop now?
