Appendix D: Differences in Windows Server 2003 Before and After Service Pack 1
Applies To: Windows Server 2003 with SP1
In Windows Server 2003 Service Pack 1 (SP1), Microsoft introduces a set of security technologies that help to improve the ability of computers running Windows Server 2003 to withstand malicious attacks from viruses and worms. The technologies include additional network protection, memory protection, and improved computer maintenance. Also included are technologies for safer e-mail handling and enhanced browsing security. In addition, SP1 includes enhanced Administrative templates for Group Policy settings. Together, these security technologies will help to make it more difficult to attack Windows Server 2003 with SP1, even if the latest updates are not applied. These security technologies together are particularly useful in mitigation against worms and viruses.
This white paper provides information about some of the improvements in Windows Server 2003 SP1 as compared to the original release of Windows Server 2003. In particular, Appendix C: Group Policy Settings Listed Under the Internet Communication Management Key provides information about some of the Group Policy settings available only in SP1 and later. These settings are designed to provide specific ways to control the way components in Windows Server 2003 with SP1 communicate with the Internet.
