From the bungie help files
Establishing the connection between your Xbox Live Gamertag and your online .NET Passport is a simple, one-time-only process, that can only be accomplished through the Xbox.com website.
What you'll need:
A .NET Passport account (make sure this is the same one you're going to be using at Bungie.net)
Xbox Live Account
To verify your identity on Xbox.com : (all of these are available through your Xbox dashboard)
Name of credit card holder on the Live account
last 4 digits of the credit card
phone number
postal code
Once you're ready, head over to Xbox.com to the "Link Gamertag" page. You'll be prompted to first sign in with your .NET Passport. If you're a first time visitor to Xbox.com, you'll have to accept their terms of use and create a quick account. (just your email address).
Enter the required information, click on "continue" and voila' - you've just linked your Gamertag!
If you have any problems with this process, follow the support options given on Xbox.com.
hope this helps.
