XP SP2 Frequently Asked Questions: Continued from Part 1 ... Q: " I already have Norton Internet Security installed and running.

Computer tries to access 127.0.0.1?

Infopackets Reader Frances D. writes: " Dear Dennis, I have a problem getting my home page as well as other web pages to pull up. My email pulls up, and sends fine. Sometimes, when I access Internet explorer, it tries to connect, but then reports an ... error message. Other times it will slowly pull up and stop at the half way mark. It tells me it is connecting to site 127.0.0.1. What the heck is site 127.0.0.1? I have contacted my Internet Service Provider and they have told me a number of things to try, but nothing has worked. Is this my computer or is it an Internet problem? " My ... (view more)

Earlier this week, I informed Readers that our web server was assaulted with a Distributed Denial of Service ( DDoS ) attack. After writing Tuesday's article, I invited some comments from Readers concerning the attack.

For this reason, I believe that the attack on your server was ... (view more)

If I say "No" when permission is requested, it comes up 'unable to connect to that site', which leaves me with the only way to browse the site by clicking on "Yes."
