There have been a few of these handy Best Practice analysers that MS has released over time. So now Sharpeoint joins them.
Definetly something you’d add to your WSS 3.0 or MOSS install proceedure.
The Microsoft Best Practices Analyzer for Windows SharePoint Services 3.0 and the 2007 Microsoft Office System Best Practices Analyzer programmatically collects settings and values from data repositories such as MS SQL, registry, metabase and performance monitor. Once collected, a set of comprehensive ‘best practice’ rules are applied to the topology. Administrators running this tool will get a detailed report listing the recommendations that can be made to the environment to achieve greater performance, scalability and uptime.
