Got a little problem with Internet Connection Sharing on Windows XP that I hope someone can help me with. I have a laptop with a built in wireless networking card (802.11b) that connects to a wireless router. The router also has two other computers attached to it (one wireless, one CAT5), and a cable modem, providing all three computers with 2Mb internet access. I also have a desktop computer connected to my laptop via a cross-over ethernet cable. I wish to be able to share the internet connection I get with my wireless laptop with the desktop computer, but every time I try to share it I get an error saying "Internet Connection Sharing cannot be enabled. A LAN connection is already configured with the IP address that is required for automatic IP addressing.", despite the fact that the ethernet card on my laptop is set to 192.168.0.1, as directed. The router is currently 192.168.0.2. Both the laptop and the desktop are running Windows XP.
Thanks very much,
