Sounds more like a simple case of the hosts file having been edited. When you look up www.aol.com, your PC will try to resolve the IP address from the local hosts file and failing that, a DNS server. If the local hosts file has had www.aol.com listed with compuserve's IP, then that'll create the effect you're experiencing. More worrying is how this arose in the first place - I wasn't aware compuserve hijacked AOL in this way! Anyway, to check, and edit your hosts file, look for c:\windows\system32\drivers\etc\hosts if you're on NT/2K/XP and for c:\windows\system32\hosts.sam if you're on 95/98/ME
