we have 3 computers linked by cable and they were all fine until one of the computers became invisable to the other two machines, the problem computer can still see both the other computers and is able to use all the shared folders, we have tried running the network wizard on the computer again but we still cant see it, the share folder on the computer is set to share, i think its a firewall thing or maybe a AV prog that is blocking us, but no matter what we try we can not get to the bottom of it any help please
..and is the IP address of the missing computer in the other two as well. AS it is invisible to them it would be the other two that were blocking access. IP address of missing PC may have changed since original set-up explaining why it is now invisible. Just a thought.
