Last year, we delivered the Microsoft Exchange Server Best Practices Analyzer, or ExBPA for short. Since then we've made several upgrades to that tool as well as published monthly updates to the validations the tool does. The feedback loop that has been established between the product development team, our support engineers, and customers has been a great success and given us a virtuous cycle that allows us to continually adapt and improve the product. We hope to establish this same kind of thing for a couple of new tools we have released: the Microsoft Exchange Server Disaster Recovery Analyzer (ExDRA), and the Microsoft Exchange Server Performance Troubleshooting Analyzer (ExPTA). These two tools build on the framework of ExBPA and allow us to define a set of iterative steps to be performed to achieve a particular goal. In the case of ExDRA, that goal is to guide a user through the disaster recovery process, automating as much as possible. For ExPTA, the goal is to move from a symptom of a performance problem to a root cause and resolution.
