I bought a current model mac mini server and it arrived today. Yay.
I have a macbook pro running 10.8 and the server is connected to my router by ethernet, laptop is connected wirelessly to same router.
The mac mini is straight out of the box, yet to have it's OS set up. Yes I turned it on.
I have assigned the mac mini an ip address of 192.168.1.222 which I can verify is accessible through the terminal with $ ping 192.168.1.222 returning the expected response.
However, when I go through Finder->CMD-K I get connection failed.
My network preferences screen sharing set to on.
