Under the concept art section of media there is an object called "The Device". When it was clicked on, it popped up in a new window and requested access to the microphone and when you accepted it and played the 719hz sound file gained in Server 02 to the microphone, it opened and led you to the page with the key to unlock Server 03.

Server 04
In the Halo Insider section there is a poem named "WHEN WE TWO PARTED". Using the first letters of each line that had an extra space spelled out THECASTAWAYTHEORYVOLMAN which spaces out becomes The Castaway Theory Volman, with Volman being the author. That led to. An MSN username that was eventually revealed, profvol49 was a Microsoft bot that, after you asked some questions, led you to the page with the key.
