so i am up to helping/resolving problems windows based pc`s since is a headache to do over phone, and i am looking for something that will work instantly on pc`s connected via broadband more likely but won't have static ip on both sides therefore "customer/friend"(ppl that got no idea of finding their ip address) won't be able to tell me his ip each time .
so is there anyone that can refer me to something?
