I'm running my server on a net book and the game on my desk top (trying to at this time) but i might be able to help a bit. What the guide says is to set your EQ game to 127.0.0.1 and that works if the game is on the same comp as your server. If you want to LAN party your going to need to set your Servers comps personal IP address. I used this site
http://www.tp-link.us/article/?id=14 and then set your EQHost file to that IP address. Hope that helps.
