Oh, and in addition to my other post in this thread, you
may want to confirm that your DNS server setting is set
for the correct server. Bad guys have been known to
change this to one they control the data of - just like the
hosts file, they provide a wrong number in return for
a lookup and then can "spoof" the site you intended to
reach at this new fraudulent IP address.

Not too helpful I'm afraid, but you asked for ideas.

I am unable to access www.equifax.com using my Vista Ultimate SP1 system.
Both IE7 and Firefox are unable to connect. I am running Norton Internet
Security 2008. No other sites I have tried to access are blocked. I have
checked for restricted sites in IE settings and have disabled all NIS
protection. Parental controls are not turned on. I am able to access the
site using two other systems on my network that are running XP SP2 with NIS
2008. Any ideas what is blocking this site?
