Yo! I've had this recurring problem with Leopard's Finder. I'm running a mac pro. The Shared section keeps showing me machines or routers that either aren't there or aren't accessible. Look at the image I attached, I sold the MacBook Pro a week ago, and its been showing up in SHARED even though its long gone. And this second 'airport-extreme' listing is confusing me. Obviously the top airport extreme is the real one, but what's with this second one showing up?! Its even showing it as a PC! I have restarted many times since the MBP was here. Oh man, I hope someone out there can shed some light on how to get these two rogue "shared devices" outta my finder... Bring the miracles please!
