Hey, I have a macbook pro running on snow leopard 10.6.6. I have trouble with the connection between a macbook and my macbook pro. Every time i try to connect with any other macbook('s), i keep getting the "connection failed" message. I try to connect as guest or registered user and neither of them will work. Maybe i'm doing it wrong, i've already gone to system preferences > sharing to try to fix it, but i really can't make it work. I hope someone can give a helping hand, thanks a lot.
