Best Practices Analyzer tool (Office SharePoint Server)

You can run the Best Practices Analyzer tool to check for common issues and best security practices. The tool generates a report that can help you optimize the configuration of your system. The tool can be run locally or from a server that is not attached to the server farm.

I generate a report by using this tool on test server then it look like given below.
It shows your Errors & Warnnings.....what you are missing on your server e.g as i have not configure out-going email settings, Trusted DCL's on servers.
You can download it from Microsoft Official Site...Click here to download

Simply a tool which helps to help administrators to achieve greater performance, scalability, and uptime........So, be ready and start generate reporting.
