• The Debug Diagnostic Tool (DebugDiag) is designed to assist in troubleshooting issues such as hangs, slow performance, memory leaks or memory fragmentation, and crashes in any user-mode process. The tool includes built-in analysis rules focused on Internet Information Services (IIS) applications, web data access components, COM+, SharePoint and related Microsoft technologies.
