I have a Windows XP computer on my network. I can no longer see the network hard drive attached to Airport Extreme from the XP computer. I can see it with all the MACs on my network and all the Windows 7 computers. I can connect to the internet with the Windows XP computer. I previously had no problem seeing the network hard drive attached to the airport extreme from the XP computer and one day it just disappeared. I have deleted and reinstalled Bonjour, not just Bonjour print services. I can print to a network printer that is not attached to the Airport Extreme. Help!
