Here's my problem: I worked on my friend's computer. I installed my LAN card in his PC, and set up his LAN settings, then downloaded all the latest Windows Updates (which he had never done), then took out the card and uninstalled the card's drivers. I also unchecked proxy server, rechecked "always dial up my default connection."

Now he can't access the internet. He can dial in and connect to the internet, but when he opens IE he gets the "page cannot be displayed error."

I know this problem has to be fixable under "Internet Options" then the "Connections" tab. The question is, where?

Setup a new Internet connection?
Dial up network settings?
TCP/IP settings?

Needless to say, he was very disapointed that he wasn't able to get online. What should I tell him about fixing it?

Thank you so much!
