In Windows management, best practices are guidelines to configure a server as defined by experts. For example, it is considered a best practice for most server technologies to keep open ports that are required for the technologies to communicate with other networked computers and also block unused ports. Whereas best practice violations, even very important best practice violations, 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.

More Information

What is the Best Practices Analyzer?

The Best Practices Analyzer (BPA) is a server management tool that is available in Windows Server 2008 R2. BPA reports best practice violations to the administrator after BPA scans the roles that are installed on Windows Server 2008 R2. Administrators can filter out unnecessary information or exclude results from BPA reports. Administrators can also perform BPA tasks with either the Server Manager GUI, or Windows PowerShell cmdlets. For more information about Best Practices Analyzer and scans, see the Best Practices Analyzer Help.

About the Hyper-V BPA update

The update described in this article contains best practice benchmarks against a computer that is running Hyper-V on a computer that is running Windows Server 2008 R2. After this update is installed on a server that is running Windows Server 2008 R2, you can run a series of Best Practices Analyzer scans on Hyper-V that will help you to bring the role into compliance with best practices.

You can use the Hyper-V Best Practices Analyzer to scan a server that is running the Hyper-V role, and help identify configurations that do not comply with best practices for this role. BPA scans the configuration of the physical computer, the virtual machines, and other resources such as virtual networking or virtual storage. Scan results are displayed as a list that you can sort by severity, and include recommendations for fixing issues and links to instructions. No configuration changes occur automatically by running the scan. For more information about Hyper-V, visit the following Microsoft website:
