What is Best Practices Analyzer?

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 don’t need to see. Administrators can also perform BPA tasks by using either the Server Manager GUI, or Windows PowerShell cmdlets.

DHCP Best Practices Analyzer

You can use DHCP Best Practices Analyzer to scan a server that is running the DHCP role and help identify configurations that do not comply with the best practices from Microsoft for this role. BPA scan will examine the DHCP server configuration and identify potential issues such as incomplete or incorrect configuration of DHCP scopes. Identifying and fixing these issues will help in improving reliability, performance of the DHCP server and avoid potential network issues. Scan results are displayed as a list of issues that you can sort by severity, and include recommendations for fixing issues and links to instructions. No configuration changes are made by running the scan.
 
Some of the examples of checks performed by the DHCP BPA scan:
 
A Forward lookup zone should be configured for the DNS domain used to register DNS records for IPv4 clients
Secure DNS updates should be configured if Name Protection is enabled on any IPv4 scope
The MAC address filtering configuration should not block IP address reservations
Credentials for DNS update should be configured if secure dynamic DNS update is enabled and the domain controller is on the same host as the DHCP server
