ethernet cable? I was thinking i could do this via an ad hoc network? I dont need anything perminant, just a quick fix. How can i use my laptops internet connection (gained through wifi) to give my desktop internet? Desktop has no wireless pci card or anything, so it would need to be through my ethernet cable. thanks.
opps: Both run on vista and its a Dell 8400 Dimension and a Dell M1530 XPS

Jimmy20! Thank you that worked perfect! Heres what i did for anyone else interested. On my laptop in Network Connections i selected both my Wifi connection and my LAN connection (after having connected both the PC and LAPTOP via ethernet cable). Right clicked one of them whilst both selected and pressed bridge connection. Then waited a while, and BAM! PC has internet borrowed from laptop!
