I set up a lan with 3 computers. Two desktops and one laptop. All are running windows xp pro. All are in same workgroup. All can recognize each other. Computer A can see and read shared folders on computers B, & C. C can read B, B can read C. But when I try to read from B or C to A I get" ...is not accessible. You might not have permission to use this network..." I am running in simple file sharing, I have netbui installed as default protocol. A & B both use Kaspersky firewall, C uses AVG. I am at a lose as to what to try to get all working with each other. Any recommendations? Thanks - I am new to this forum.
