I have a Mac mini running Mountain Lion 10.8.2. I reboot this machine holding down the "N" key. It starts and I see the Globe icon. Then, after a minute or two it just boots up regular and I see my standard log in screen asking me to enter my Administrator password.
What causes this? I know this machine is on the network since once I log in I can apple-K and connect to other machines and I can get onto the Internet.
