My sister in law is having an issue. She JUST got her first iPad, an iPad2. She runs Windows Vista home edition, and she has the updated iTunes 10.2.1. However, when she plugs the iPad into her iTunes, she gets a "iTunes cannot connect to the network, check your network settings." error message. She can't get into the iTunes store either. She can easily access the web and various sites via her IE. Any suggestions for trouble shooting this? Thanks!
