Shared computers on Finder unknown

I am at a loss to explain why I have two new shared computers or servers on my shared network at home. I have an Imac as well as a two laptops and my son's Windows computer. The two showing up are none of these. My network is passwork protected. I have a Airport Extreme with WPA2 personal. I also have a guest network setup albeit with an easier password. I also have file sharing, itunes sharing, and even screen sharing between my computers. If I try to connect to the one named brne16a51 it says unable to connect. The other one (kenneth-wsl8gcw) asks for a registered user (providing name and password) or connecting as a guest.

Please help.

Yes one could be my iphone. It has my name kenneth in the name. My wife's says her phone is off wireless now, but brne16a51 I guess it could be her work phone possibly.
