I just installed windows XP into my old dell computer. After a lot of debugging (cannot detect wired or wireless cards), I could finally ping any website from the cmd window. However, there are problems with the Internet explorer. I got error msg "Windows cannot connect to the Internet using HTTP, HTTPS, or FTP. This is probably caused by firewall settings on this computer. Check the firewall settings for the HTTP port(80), HTTPS port (443) and FTP port (21)." Then I went to the "Lan Setting" and make sure the proxy server box has no checks and everything is blank / unchecked on the page. However, I still get that error message.
Any help would be appreciated on solving this problem.
