I have 2 Windows 7 boxes (one laptop and one desktop) plus a vista machine and a Windows Home server. All but the Home server is connected via a wireless connection. All machines can access the web, etc. however only the home server is visible on the network (and the home server can access the other 3 machines). I cannot ping (by name or IP) any of the other machines and they don't show up in Windows Explorer. Before I put Windows 7 on the laptop and desktop everyone could see everyone. I tried creating a home group from the Win7 desktop and joining that from the laptop but the home group is not found. I also played with changing the wireless network from a "home network" to a "work network" without any luck. the Win7 installs were clean installs not upgrades. Any ideas?
