iTunes cannot connect to the update server

My iTunes version is 10.6.0.40.

I cannont connect to the iTunes store or any of the update servers.

I've tried many solutions offered on the support forums as well as microsoft's support forums.

My network works fine for everything else... streaming video, playing multiplayer games, browsing web, purchasing products etc...

Any help is much appreciated.

Solutions tried:

Setting LAN to "automatically detect settings"

Clearing my "SSL state"

Flushing my DNS

Changing DNS servers

Restarting router

Configured router to accept iTunes

Resetting all internet explorer settings to default

Creating a new administrator account and using iTunes through it

Disabling all internet security programs

Disabling firewall

Checking the windows hosts file for apple update servers (none are listed, so this is fine I suppose)
