One of the things that you will have to do is change your IP address which is hard to do and if you can not do that then you will more then likely have to start a new account.
To find out if your xbox has live on it simply sign into one of your accounts, if the account does have live, it will say so. If not, you can purchace live at any time.
All you have to do is create the account and it automatically becomes what is call an Xbox Live Silver Account. You don't need any credit card or subscription card.
Unfortunately, once an account has been banned from Xbox Live you cannot access any downloadable content that you may have had. When the account was banned all DLC was lost.
Yes, Halo 3 supports multiplayer Xbox Live gaming for any one with an internet connection and a xbox live Gold account
Yes, you can close your Xbox Live account without closing your Microsoft account. To do this, you need to go to the Xbox support website and follow the instructions for canceling your Xbox Live subscription while keeping your Microsoft account active. This will allow you to retain your Microsoft account and any associated reward points. Just ensure that you do not delete the entire Microsoft account during the process.
When your game indicates that you don't have the necessary privileges to access Xbox LIVE gameplay, it typically means that your account may not have the required Xbox Live subscription, such as Xbox Live Gold, or that there are restrictions on your account. This could also be due to parental controls, account suspensions, or privacy settings that prevent online access. To resolve this, check your subscription status, account settings, and any restrictions that may be in place.

You can check on your Gamercard in the My Xbox screen of the Xbox Dashboard. If you are signed into Xbox LIVE, it will display "Signed in - Xbox LIVE Gold" or "Signed in - Xbox LIVE Silver" on the bottom of your Gamercard.
there is nomore xbox live on old xbox onily on xbox 360 and if you play xbox live on the 360 you can use 2 players 1 w/xbox live and 1 w/no xbox live
No, you do not need Xbox LIVE to play any original Xbox games. Not all original Xbox games can be played, but Halo and Halo 2 do not need LIVE to be played on the Xbox 360. I just now tried it with my LIVE unplugged and signed in to an offline account and it let me play both of them. The previous answer was a lie, obviously.
