Answer 1

Problems connecting to the iTunes Music Store often
stem from issues with the Windows firewall or a
firewall in a router, a privacy filter (such as
McAfee Internet Privacy Service or Norton Internet
Security), an antivirus/antispyware utility, or a
download accelerator. Start here:
iTunes for Windows: Overview of Music Store
Errors
for some basic tips to start isolating the cause of
the problem. What you need to do is temporarily
disable any such service and see if that fixes the
problem. If so, then if it's a firewall/Internet
filter that's causing the problem and you'll need to
set the offending service to allow iTunes to connect
to the iTunes Music Store.
Hope this helps.
so, you're saying to start isolating other things as you mentioned and see if itunes begins to work normally?
