I’ve heard that installing AOL will change communications settings. Is that true, and if so how can I fix it? I recently had a problem with a colleague’s home computer. He was able to use dial-up networking to connect to our network from his home computer. He thinks one of his kids insalled a new version of AOL and now neither he or his wife can dial in from home. The modem won’t even dial. But he said AOL still works.
