Sorry, I never told you how to do my suggestion did I? Must have missed the post :) You need to go into the admin interface -> users tab -> choose "roles" from the menu to the left -> click on the assign button (paperclip icon) for Intranet -> click the radio button for anonymous -> click select.
You (should) then not have to login. Unless there's something in the templates that make the login box come up when you're not the correct user.
