Itunes will not connect to Iphone update server or CDDB Server
Recently, not sure when it started, my laptop (Windows 7) has been unable to get track information, and unable to "check for iPhone updates". I can connect to iStore with no problem, and even download app updates. I've tried everything I can think of, including disabling firewalls. My programs are up-to-date, and all software is legit (no jailbraking). Please help.
BTW: I can connect at work on WiFi without incident, but at home I use an AT&T wireless card.
iPhone 5, Windows 7
