I am running two Macs with OS X 10.5.8 on both. Until recently I was able to browse between the two and use remote sharing, however this no longer works. Nothing shows up in 'network' in Finder, and if I try to connect to the computer by name, I get an instant 'connection failed' message with error code 36 and the following text: 'The Finder cannot complete the operation because some data in "afp://......" could not be read or written.' I've also tried connecting to one of the items in my 'servers' recent items list, and that doesn't work either (no error message is generated). I am thinking this may be a router-related problem as our router recently had its firmware upgraded, but I have no idea where to start troubleshooting. Both computers are on the same wireless network and the signal is strong. I can ping between both computers without issue. Any help would be much appreciated!
