Hi all, sorry for what is probably a particularly mindless question.
I've got a peer-to-peer network comprising two PCs and my ADSL router,
connected via a switch. I've got a problem that's never occurred before
and that I can't explain. Neither PC can find the other. Each is
connecting normally to the Internet via the ADSL router. Each PC can
ping itself and can ping the router, but can't ping the other PC
("Destination Host Unreachable"). Telnetting from one PC to the other
gives "No route to host". Neither PC is running a firewall.
What have I missed, and what has happened?
