Cannot connect to the iTunes store. Get 'Error 11222'. Claims it is being blocked by Windows Firewall when it is allowed through.

Question

When an external application tries to connect to it through iTunes I get 'Error: 11222'. When I try to connect through the iTunes app it just continuously loads but nothing appears. Diagnostics says that Windows Firewall (Which is being managed by McAfee) is blocking it, even though it is allowed through both firewalls I have. Even when I turn WF off iTunes claims it is being blocked by it. I have done almost everything Apple's support pages have suggested but nothing has worked. I'm using it on an Acer Aspire laptop, and the main PC can use iTunes without trouble so it isn't the ISP. I have uninstalled and reinstalled iTunes twice. Here is a full diagnostics:

Answer 1

The 11222 errors can sometimes be produced by LSP trouble. One of the suspects with that is some versions of McAfee Family Protection. For troubleshooting advice, see the following document:
