I'm using a Macbook with Snow Leopard and my roommates are using the same macbooks too and we can't get the sharing to work.
I've checked the sharing settings under preferences and I've followed the help from Apple.com. Everything seems to be configured correctly. I've even used Bonjour to see if that might show the others on the network but nothing. Also, the firewall is turned off.
We're on the same wifi network.
What could I be missing that won't make it work?
Also, under iTunes, the computers used to show up but they haven't even showed up on there for home sharing.
What's the best way I can troubleshoot this?
Edit: I'm on a home network, with 5 computers connected. There's 3 macbooks and 2 windows laptops, but this isn't really about the PCs.
