The spreadsheat at the Group Policy Settings Reference for Windows XP Professional Service Pack 2 Release Candidate 2 contains:

"Group Policy Settings Reference
Version 1.03 (Windows XP Service Pack 2 Release Candidate 2)

This spreadsheet lists the policy settings for computer and user configurations included in the Administrative Template (.adm) files delivered with Windows XP Professional Service Pack 2 Release Candidate 2. The policy settings included cover Windows 2000, Windows XP Professional, and Windows Server 2003. These .adm files are used to expose policy settings when editing Group Policy objects (GPOs) in the Group Policy Object Editor (also known as GPEdit).

Each .adm file is represented by a single worksheet within this spreadsheet. In addition, an "All" worksheet is provided for ease of reference. By using the ADM Parser utility (admx.msi, available from the Microsoft Web site), it is possible to import custom .adm files into the spreadsheet to better reflect your own environment. See the ADM Parser utility help for further details.

You can use the filtering capabilities included in this spreadsheet to obtain a specific subset of data based on one or a combination of values available in one or more of the header categories. In addition, you can select Custom in the drop-down list for any of the header categories to add additional filtering criteria within that category. To obtain a specific subset of data, click the drop-down arrow in the header cells that contain the value, or combination of values, on which you want to filter, and then click the desired value in the drop-down list. For example, to view a subset of policy settings that are available through the Inetres.adm template and viewed under the Computer Configuration node, select Inetres.adm in the .adm File drop-down list and MACHINE in the node drop-down list."

NOTE: The Update History tab contains all the changes since the release of Windows Server 2003.
