List of SCCM and MDT 2010/2012 Variables

There are three ways to get the list of variables that MDT uses:

1. Technet has a comprehensive list of the SCCM/MDT variables located here.
2. Michael Niehaus has a script that will dump all of the variables to a text file located here.
3. This is the method I use. A SQL database will need to be created and linked to the MDT. Once done, click on the Roles subtab. Click New and select Details. All available variables will be listed.
