The game was out before Xbox LIVE was created so you can't use it like Halo 3.
There is an alternative by using System Link. XBConnect features a way to play Halo CE, Halo 2, and other games online through Sys. Link.

On there you can follow the requirements to play online legit through Sys. Link. My account and gamertag is the1upDude.
Hope this helps!
You can download a demo version of Halo: Combat Evolved for free on the internet. There is also the Halo: Custom Edition, but this requires the CD Key of the full version of Halo: Combat Evolved installed on the computer you install Custom Edition on. Custom Edition is free, and allows for the use of user-created maps. It does not include the campaign though.
At this precise moment, it is currently unknown. Halo CE Anniversary will, however, use the original halo's campaign levels, but will use the multiplayer system and indeed servers from Halo: Reach.
Yes!, Halo is cool
I would assume you install it.
Well, Halo Custom Edition is the multiplayer version of Halo Combat Evolved PC. It doesn't have a Campaign, by the way. If you want to get Halo Custom Edition, install the installer and use your Halo Combat Evolved PC Key. The main advantage of Halo Custom Edition is custom maps. Halo Custom Edition is currently in Version 1.0.9.620
The product code for halo custom edition is the same code for the original halo combat evolved, if you don't have a code, you can find used codes throughout the Internet, just use one that you see somewhere, it doesn't effect the original buyer.

Yes you can use it. I used it myself to play piller of autumn in halo.

Don't die and go slow. Use plasma weapons.
