In my new pc I have 2 inbuilt network cards. One is connected directly to the router and the other is connected to my old pc with a crossover cable. I am using the old pc as an emergency backup in case my new one stops working, and also to transfer music & data files across as a third backup system. At the moment this old pc has no direct connection to the internet. I noticed in the properties of the second inbuilt network card on the new PC that LnS has added itself as a driver. I have disabled this (unchecked it). Is this the correct thing to do ?
