Thanks - got simple file sharing turned off, completed the tutorial, but networking only worked until I rebooted. This morning the same problem has returned.
I can sometimes see other computers on the network, but can't doubleclick one to access files. When I do, the error "<computer name> is not accessible. You might not have permission to use this network resource. contact the administrator of this server to find out if you have access permissions.
The network path was not found" appears. This happens on both computers, and it has been the case since I bought these and tried to network them a few months ago.
I'm interested in following up your suggestion quoted below, but how do I find the right KB article? I will try search but thought you might remember how to find it?
Thanks, Jwinathome, any help is appreciated
