Static configuration inspection; no server connection

Review before downloading
Treat configuration findings as a migration checklist.
This is a static inspection, not a complete IIS configuration validator. Parent configuration, locked sections, server permissions, installed runtimes, and actual module availability cannot be inferred from one file. Input stays in your browser and is not included in the downloaded report. Redact connection strings, passwords, and tokens first. Limit: 2 MB. Back up and test any configuration changes on the target server.
