My friend and I are trying to set up a homegroup on a network so that we can share files. He has Norton Internet Security, and I have Norton Security Suite. We're both running Windows 7. We had it working before, so I'm not sure what changed. Now, I can see his computer on the network, and he can see mine, but we cannot access each other's files. Is there something we need to fix in the firewall setup, or are we missing something here? Ideas, anyone? TIA
