Yes, they're on the same subnet (192.168.1.2 and 192.168.1.3, each with mask 255.255.255.0). Each of the PCs has an NFS folder which is ordinarily mountable on the other, but when I try mounting either NFS folder from the remote machine, I get "mount - RPC: Port mapper failure - RPC: Unable to resolve". (I suppose that's logical, if the machines can't see each other.) We're just back from a couple of weeks away, during which time the computers were kept switched off. They had been fine previously. I don't see how a hardware problem could let each computer talk to the router (192.168.1.1) but not to the other computer; the communications are going through the same ethernet cards (located at eth0 on each machine), cables and switch. =====Andrew
