Overview

The Microsoft Windows Small Business Server 2003 Best Practices Analyzer examines a server that is running Windows Small Business Server 2003 (Windows SBS) and presents a list of information and errors that administrators should review.
The Windows SBS Best Practices Analyzer examines the server and collects configuration information from many sources including:
• Active Directory Windows Management Instrumentation (WMI)
• Registry
• Metabase
After collecting information about server configuration, the Windows SBS Best Practices Analyzer verifies that the information is correct and then presents administrators with a list of issues sorted by severity. The list describes each issue and provides a recommendation or possible solution.
