I am on Dell desktop computer that is running on Windows XP. Earlier, while I was surfing the net it started running very slowly. I rebooted but it would not let me to use the internet. I ran Windows XP Network Diagnostics but I got this message:
How to fix this issue?Windows cannot connect to the Internet using HTTP, HTTPS, or FTP. This is problem caused by firewall settings. Check the firewall settings for the HTTP port (80), HTTPS port (443) and FTP port (21)
