Service Pack 1 (SP1) for Windows Server 2003 was released by Microsoft on April 6, and the many benefits of this upgrade are now being weighed against some minor and not-so-minor incompatibilities it introduces.
Containing significant security improvements, as well as nonsecurity updates, 2003 SP1 has several things going for it:
• The Security Configuration Wizard helps server administrators disable unneeded services and close ports that are invitations to hackers.
• An improved Windows Firewall now shuts off inbound Internet connectivity while setting up and during bootup and shutdown to provide additional protection against intrusions at vulnerable moments.
• VPN Quarantine allows you to deny access to PCs that connect to your servers via virtual private networks but are not up-to-date with security software you require.
