Nothing different on either computer. We had the Network, set up and working, and then suddenly a couple of days ago we got this problem. The only thing we can think of is we did do Windows updates, but can't remember now whether that was before the problem or after! We are sure it is just a setting got changed somewhere but what?! We have tried setting up a new wireless network, and also an Ethernet network and still get the same results. Logically if the network is working then provided we have ICS enabled on computer A it should work.Cheers ColnPam
