From my new Macbook Pro i can see the computer name show up on the Network, but when i try to access it, it never connects. I am not prompted on the Vista32 computer with ESS to allow anything and the Macbook is definitely in the trusted zone. My Xbox in the same trusted zone can view the shares fine. I have had the same issue with Beta 2 and RC1 in both automatic filtering and interactive filtering modes. If i disable filtering the Macbook can connect and view the shares perfectly.
