Microsoft provides an excellent tool called Group Policy Management Console (GPMC). It enables you to view the group policies objects, where and the order they are applied to the different OUs. Together with Active Directory User and Computer you can assess the impact of Group Policies on the user computer.
I discovered another tool, that enables you to document Group Policies that applied to the user computer. In Start, Help and Support. In the window, locate the search box and enter “Advanced System Information” Click on the link “View Group Policy settings applied”
All the GPOs applied to the computer and the user account can be seen. Scroll down to export to HTML or print.
Note you can do this for Windows 2003 or XP.
