I have my home network all lovely, set up and working perfectly. Snow Leopard handled it all fine, however since upgrading to Lion, I appear to have two unknown computers in my finder sidebar. As you can see from my screenshot, they both begin with the letters 'hp', which leads me to believe they are HP laptops/computers. They are also un-connectable. I'm quite anal about my home network. I even have a diagram of it, as you can see, one of the laptops is present in my sidebar and I am connected to it. I have no idea what this could be but a Lion bug.
