Figured it out...thanks
Thank you for the suggestions. I figured it out. I read somewhere that when you sign in to "share library" in iTunes it sends the SSID or network name and user name information (can't remember for sure). Anyway, I recently bought a new wireless router and for some reason Windows 7 decided to keep the name of my old network as the active network but updated all the other new network information. I simply went in on the host PC and changed the name of the active network (where the bench icon is in Network and Sharing Center) and then it matched my iPad (which was set up correctly to connect in the first place). I guess the moral of the story is to make sure the iPad and host PC the library is on have matching network name, etc. information. Why Win 7 would keep the old network name is a mystery to me...but then again it's Windows.
