If anyone could please help me withthis, without giving me a runaround to support pages I've alreadybeen to,
I understand your frustration but we have no way of knowing exactly which support pages you have already visited.
Maybe your security software or Firewall...
Have you tried here? iTunes for Windows: Troubleshooting security software issues
I've started turning off the active guard from my security software whenever I open iTunes because it tends to mess with my downloads a lot and stop me from connecting to the store; it didn't really effect my iPad's connection to iTunes before, but I don't think that's what's causing this problem.
I pretty much just meant the support pages iTunes took me to for help with the diginostics and the ones I mentioned; other than that I'm not sure if there's anything I might have missed that could help more with this.
