We've updated a couple of security solutions and they went live 12.27.05:

The Threats and Countermeasures Guide v2.0
http://go.microsoft.com/fwlink/?LinkId=15159
The updated Threats and Countermeasures guide provides you with a reference to all security settings that provide countermeasures for specific threats against current versions of the Microsoft Windows operating systems.

The Windows Server 2003 Security Guide v2.0
http://go.microsoft.com/fwlink/?LinkId=14845
The updated Windows Server 2003 Security Guide provides specific recommendations about how to harden computers that run Microsoft Windows Server 2003 with Service Pack 1 (SP1) in three distinct enterprise environments.
1. where older operating systems such as Windows NT 4.0 and Windows 98 must be supported.
2. where Windows 2000 is the earliest version of the Windows operating system in use.
3. where concern about security is so great that significant loss of client functionality and manageability is considered an acceptable tradeoff to achieve maximum security.
