Hi, I always had issues with file sharing on my home network. Sometimes it works sometimes it just doesn't. I own a 2007 iMac and a 2012 rMBP.. both are running Mavericks at the time (same build). I have file sharing turned on on each one of them with both AFP and SMB on. First of all, in Finder, I can't see the iMac on the Shared section on the sidebar nor I see the rMBP on the iMac. If I try to connect to the server directly I always get this error: I may try connecting using the 'xxxxxx-iMac.local' server name, 'afp://xxxxxx-imac.home' or 'smb://xxxxx-imac.home' and I almost always get the same error. Yesterday I tried and it worked fine.. today I tried and it doesn't. Here's my configuration.. it is the same on both Macs: Please help..
