Can no longer access Itunes store

Question

Sudeenly yesterday I cant access the Itunes store. 
When I click on the store, I just see the scrolling barbers pole at the top of the screen and the message ""Accessing Itunes store."" It never gets any further
Ive disabled all my security, ive done the winsock reset and restarted my PC ((many times) I downloaded the LSP list from windows, and the list is huge, with many suppliers listed. It would take days to try and update all of that.
SURELY there is an easier solution to this problem. Clearly Im not the only one having it.
Please help

Answer 1

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:
