DTLknowsWhy is a Windows diagnostic and expert analysis tool designed to help administrators, technicians, and support engineers understand not only what is happening on a system, but also why it is happening.
The project combines automated system inventory, configuration analysis, and expert knowledge to identify potential causes of common Windows issues involving networking, services, SMB sharing, name resolution, security products, and system configuration.
DTLknowsWhy is intended to evolve from a data collection utility into a true troubleshooting assistant capable of explaining observed symptoms and suggesting probable causes.
Late Breaking News: 19-jul-2026 - DTLknowsWhy will be superseded by DTL4u. Stay tuned.
