HiCustomer Thank you for asking your question on JustAnswer.
First, download all the Windows updates again. If you are able to access the web, but you are unable to access the iTunes Store, see the troubleshooting steps below (My apologies in advance of some of these were already attempted).
iTunes Store, iTunes, Windows 7, Windows Vista, Windows XP, Microsoft Windows XP SP2 and Vista
Some pop-up or ad-blocking programs may interfere with the ability of iTunes to connect to the iTunes Store. Removing them in many cases will resolve the issue.
In some cases, the DNS information you computer uses to connect to the Internet needs to be reset. Follow these instructions to flush your Windows DNS information:
If iTunes is out of date, it will not be able to connect to the iTunes Store. You can download the latest version of iTunes from our website:http://www.apple.com/itunes/download/
Windows XP Service Pack 2, by default, enables the Windows Firewall. As with a third-party firewall, you will need to configure Windows Firewall to allow iTunes to access the iTunes Store. To do so:
If you have further questions about configuring the Windows Firewall, contact Microsoft's Service Pack 2 hotline at (888) SP2-HELP. Read this article for compatibility information.
Windows XP: C:\WINDOWS\SYSTEM32\DRIVERS\ETC
Sorry, none of these works. As I said I had tried that "host" file replacement. I did the FlushDNS thing as outlined, but figured it wouldn't anything, as the OS install is fresh (this morning!). As expected, it did nothing. As far as the firewall exceptions, itunes is already checked by default, so that wasn't it. Could the problem lie in a setting in my antivirus software---iolo?
Make sure both iTunes.exe and iTunesHelper.exe are not blocking access. To make sure that your firewall is not blocking iTunes:
I don't think this would be related to Anti-Virus, it seems more related to permission errors, such as provided by a firewall.
I think I'm not looking at quite the same screen as you. Steps 3-6 don't jive for me. See screenshots...
2. Double-click Internet Connections
3. Right-click the network interface you use for Internet access and from the shortcut menu choose Properties.
4. In the Properties window, click the Advanced tab.
5. In the Windows Firewall section, click the Settings button.
6. In the Windows Firewall window, make sure that the "Don't allow exceptions" option is not selected, and then click the Exceptions tab.
Sorry about that. I meant to access the Windows Firewall
To adjust Windows Firewall settings
Click Start and then click Control Panel.
In the control panel, click Windows Security Center.
Click Windows Firewall.
In the General Tab make your selection.
Go to Exceptions Tab
In the control panel, click Windows Security Center, else go to step 3.
It doesn't work. Itunes was already in the list and was already checked. When I went to Add (just for the hell of it) and browsed to Itunes in the Program Files directory, it told me that I couldn't add it because it was already in the list.
Could the problem be from some kind of interference from drivers? I'm working on a T43 IBM Thinkpad and after installing the OS this morning I loaded the driver files from a disc (which I had copied off of Lenovo's website a while back, and are supposed to be compatible w/ my machine). Could one of these be the problem?
Or is it maybe the iolo antivirus software? Besides that I can't think of what other programs might be interfering with it---I have very few loaded so far. No ad software or special pop-up blocker software or anything like that...
I am not sure what it could be at this point. I am going to opt out and allow some other experts an opportunity to share their knowledge.
Try calling Apple Support. They probably are questioned about this often.
