Problem started after I installed AOL 7.0. Even after completely removing AOL the problem persists. While I can login to either of my two ISPs and I can PING an IP address directly, I get an unknown host error when attempting to PING by domain name in a DOS box and a DNS error when pulling up a web site by domain name. I completely removed the Dial-up Networking function (Add/Remove Programs, Windows Communication options) and then reinstalled it. I reinstalled TCP/IP and Dial-up within Control Panel Network. Still the same -- cannot resolve domain names. AT&T had me hard code their DNS IP within the Dial-Up Icon TCP/IP settings but it seems to not take. I tried to get an update for Microsoft's Dial Up Network (MSDUN13.exe) but it told me to use the Add/Remove Program function. I even reran the complete Win98SE install and still no go. Could I have screwed up my WinSock or some other TCP/IP related function so that it does not use an external DNS to resolve domain names? HELP!
