I am not sure what changed but my previosly working home network has one computer that cannot access the other two from network places nor can it be reached. I get a not accessible error. You might not have permission... These are all XP pro computers and the network had been working well for a few months.
The other two computers can access it and it can access the other two by IP address but not by computer name. I have not installed a firewall and I have tried turning off the xp firewall completely, although it had been working with it on and the file and sharing exception, without success.
Before I spend too much time going down blind alleys or doing unnecessary reinstalls I would appreciate troubleshooting guidance. I have been able to map network drives to the shared folders but I would rather know what the problem is with network places and fix it if possible.
