I'm trying to solve a friend's problem with his internet connection but have run out of ideas. On both win98SE and XP (he upgraded), when he opens a browser window and types certain addresses (i.e. yahoo.com), half of the time he'll get the "could not find www.addressname.com" error message. I tried flushing the cache and the DNS cache. I forgot to try only typing in the IP address instead of the domain name. Does anyone know of this problem or how to fix it? He's on an Alltel DSL connection. Thanks.
