It means you dont have a secure connection to the internet and halo 3 server can locate it. you need a better provider
probably because your computer is to old to handle online play or the halo may have a virus on it, update your computer to new software

Halo Combat Evolved fans, brace yourselfs for bad news: Multiplayer servers on Halo 1 will never work again; Gamespy, the software running the first Halo, has gone out of business; It's out of date. -R.G
When does the halo move come out?
Its cool but Halo reach is better and when Halo 4 comes i cant imagine how it will be:)

It does not come with Halo: Combat Evolved or Halo 2.
You have to create your own LAN/Internet server in the Multiplayer menu.
You cant. That was removed in the transition from Halo 2 to Halo 3. Bummer huh
