We are trying to set up a home network where all computers can see shared files on all other computers.
So far we've got two computers connected via a wireless router/modem, connected via ethernet cables. Both computers are running windows vista.
Computer A can see all the shared files on computer B.
Computer B can't see the shared files on computer A. Computer B see that computer A is on the network, in network map. But computer B can't ping computer A.
A and B are in the same workgroup, and on the same network.
