There is a wired work LAN network with 4 computers on it. The workgroup name is the same on all of them. Three of the computers are Windows XP computers and one is a Windows 7 computer. Not all of the computers can see each other. Here is what the different computers can see:
- XP 1 can see XP 2 and XP 3 but not W7
- XP 2 can see XP 3 and W7 but not XP 1
- XP 3 can see XP 2 and W7 but not XP 1
- W7 can see XP 2 and XP 3 but not XP 1
Pings go through both ways from XP 1 and W7 to each other.
On W7, network discovery is on, file and printer sharing is on, and public folder sharing is on.
How can I get XP 1 to be seen by all of the computers and to see W7?
