The Forefront Unified Access Gateway (UAG) Best Practices Analyzer (BPA) tool can be run by administrators to determine the overall health of their uagshort server, and to troubleshoot issues that arise. The tool scans the configuration settings of the local Forefront UAG server, and reports issues that do not conform to the recommended best practices.
You can obtain the BPA from the Microsoft Download Center. The download includes a help file to provide information about BPA events.
