Sorry, I'm not sure how to describe it any better in the thread title. I'm also not sure right now if it shows up under devices or places, but yeah. My Windows XP laptop does automatically show up in finder when its connected to the internet, my desktop windows 7 PC however, does not. I can connect to it manually through cmd + k and the IP. All 3 things, PC, Laptop and Macbook are on the same network, but only with the Laptop it works like that, not with the PC. Is it maybe, because on the Windows 7 machine I need to use my username to connect? Is there no way to make it show up automatically in the Finder sidebar?
