At our office we have mostly XP computers, with a Vista laptop, 3 7 Pro and a Windows Home Server. All the computers communicate fine, except the 7 Home laptop. It can only see the 7 Pro computers and the Vista machine. It can ping all the other computers, but they will not show up in the network neighborhood. When I tried to map the server shares, it didn't work despite being able to see it under the "Other Devices".
The 7 Home laptop has network discovery turned on and all the XP clients have LLTD installed.
I can't figure out why the 7 Pro machines are having no problem, and all the computers can see the 7 Home laptop. Any help is appreciated.
