In today's regulatory enviornment, business need to be able to audit their security settings. The Group Policy Management Console (GPMC) of Windows Server 2003 lets you create HTML reports of settings in each GPO by right-clicking on a GPO and selecting Save Report. You can then print these reports and use them for compliance reasons.
Note however that the GPMC does not report on a few policy settings, particularly some Internet Explorer settings. See the release notes for the GPMC for more info about these omissions and note that you'll probably have to audit these omitted policy settings manually.
