This paper presents Tandem's approach to efficiently handling rediscovered software problems in user systems and service centers. At the heart of the approach is a symptom-based strategy to automatically diagnose rediscovered software problems. The paper discusses the development and implementation of an automated diagnosis system, experience in incorporating the automated diagnosis into Tandem's service framework, and future work.
