I have a very weird problem with my TC. My TC is configured to allow both guest disk access and user account disk access. Machine 1, runnings Windows XP Media Center, is connected to the TC via ethernet cable, and can access the disk either as guest or as the user. Machine 2, runnings Windows 7, is connected to the TC via wireless, and can ONLY access the disk as guest! It won't connect as the user, and gives me an error saying that the username/password was wrong. Why does this work with a wired connection and not wireless??
