The HTTP Error 404.0 indicates that the resource you’re seeking is unavailable; it may have been removed, renamed, or is temporarily inaccessible. Common causes include non-existent directories or files, typographical errors in the URL, or access restrictions imposed by custom filters like URLScan.
To resolve this issue, consider creating the missing content on your web server or double-check the URL for accuracy. Additionally, you can implement a tracing rule to monitor failed requests associated with this status code and identify the module triggering the error.
This particular error is generated by the IIS Web Core module, specifically during the MapRequestHandler notification for static files, with an error code of 0x80070002. If the requested URL is erroneous, correcting it will typically resolve the 404 error quickly. For further assistance, view detailed information regarding tracing and diagnostics.
