Microsoft have just published the updated Windows XP Security Guide, which provides several levels of security guidance for customers interested in hardening deployments of Windows XP for desktop and laptop clients in their environment.
This guide includes settings for Windows XP clients deployed in a Microsoft Windows 2000 or Windows Server 2003 Active Directory domain. The document also includes guidance for an environment requiring an extremely high level of security in which application compatibility or usability may be constrained. Finally, it discusses procedures for implementing Windows XP security settings in stand-alone clients.
