Here is the deal... I have a couple of macbooks and an iMac on my home network, they are all C2D machines. One of the MB is on Leopard and one is on Tiger, the iMac is on Leopard. I can connect both notebooks and screen share and file share to each other but not the iMac. However I can connect to both notebooks via the iMac. When I try to connect to the iMac after a few minutes of hanging it just says connection failed. I never get prompted for a password and the iMac has had some issues with it's keychain not remembering passwords in the past. Is it possible that the issue is the keychain? I was thinking that because the iMac can connect to any machine in my house but nothing can connect to it. So maybe it is something to do with that? After a few minutes of hanging it just says connection failed. I could also just be stupid (that is what I am actually hoping so this can be solved). Thanks for any help.
