All of suddend yesterday, one of my usual visited web page cannot be accessed. I run Network Diagnostics for Windows XP by clicking "Diagnose Connection Problems" duing IE8. The result shows
"Windows didi not detect any problems with your connection over HTTP and HTTPS, but was not able to make a successful connection over FTP. The most likely cause of this porblme is that a firewall client running on your machine is blocknig the necessary FTP ports."
What should I do in this case?
FYI, I run live update every day both for the Norton 360 and windows update.
