A buddy passed this onto me…
In Windows management, best practices are guidelines that are considered the ideal way, under normal circumstances, to configure a server as defined by experts. For example, it is considered a best practice for most server technologies to keep open only those ports required for the technologies to communicate with other networked computers, and block unused ports. While best practice violations, even critical ones, are not necessarily problematic, they indicate server configurations that can result in poor performance, poor reliability, unexpected conflicts, increased security risks, or other potential problems.
Best Practices Analyzer (BPA) is a server management tool that is available in Windows Server® 2008 R2. BPA can help administrators reduce best practice violations by scanning one or more roles that are installed on Windows Server 2008 R2, and reporting best practice violations to the administrator. Administrators can filter or exclude results from BPA reports that they do not have to see. Administrators can also perform BPA tasks by using either the Server Manager GUI, or Windows PowerShell cmdlets.
