Tools

MS Baseline Security Analyzer In response to direct customer need for a streamlined method of identifying common security misconfigurations, Microsoft has developed the Microsoft Baseline Security Analyzer (MBSA).

Qchain.exe gives system administrators the ability to safely chain hotfixes together. Hotfix chaining involves installing multiple hotfixes without rebooting between each installation. Without this tool, the only supported method is to reboot after each hotfix installation.
