I've done the instructed process of permitting file sharing on both computers, and making sure that the ethernet configures IPv4 automatically ("Using DHCP" right?), and I still can't get them to connect. I've tried manually entering the address of either computer in the "Connect to Server" window, but still no success. Any thoughts why this would be the case? Computers are in sig. EDIT: Sorry it appears I've answered my own question. Computers needed a restart - don't quite get why that was necessary, but it's working now. EDIT 2 (just to save bumping): They were connected directly by a single cable.
