    So I have two iMac 27's and a MacBook Pro in the household.

    All of them are on my network (both wired and wirless via an Apple Extreme)

    Now if I open "Finder" and look under "Shared" then - all of the mac's I expect to see appear there - but also a mystery machine - something called "imac-4431be"

    I cant connect to this Mac - and I don't know how it got there?? My house is about 400ft away from the nearest residence - so I guess I could be seeing someone else's iMac - but how did they get on my WPA protected network (and if they were clever enough to do so then I'd guess they be able to keep their machine hidden!)

    I dont understand it? I don't know where this machine is?? It could be my Apple TV or iPad or something could it?? ...or one of my iMacs was a refurb - it couldn't be a residual machine still showing??

    I'm lost!

    Most likely explanation I'd have thought. It is annoying that networks don't seem to "clean out" non active machines, my router shows old machines as well.
