You do not have permission to view this directory or page due to the access control list (ACL) that is configured for this resource on the Web server.

As hinted, a 401.3 from IIS almost always means the web server process does not have the required NTFS permissions to read the site files. Because cannot access the IIS host, the fastest route is to send a short, clear checklist to the hosting support and ask them to verify each item.

  • Confirm which Windows identity the site runs as (Application Pool identity like IIS AppPool\<AppPoolName>, IUSR, or a custom account).
  • Ensure that identity has Read + Execute (and Read) on the site folder and all files. Prefer granting rights to the app-pool principal or the IIS_IUSRS group rather than giving broad “Everyone” permissions.
  • If file ownership or inheritance is broken (files uploaded by FTP under a different account), reset inheritance or set ownership to the proper user.
  • Check web.config for <authorization> rules that might deny anonymous users, and verify IIS Authentication settings (Anonymous should be enabled for a public PHP site).
  • Ask the host to check IIS logs for 401.3 entries and Windows Security/ System event logs; enabling Failed Request Tracing (FREB) will show which account was denied.

Provide this copy-paste block to the host so they can run it (adjust the path and pool name):

icacls "C:\path\to\site" /grant "IIS AppPool\YourAppPoolName":(OI)(CI)RX /T
--or--
icacls "C:\path\to\site" /grant IUSR:(OI)(CI)RX /T

For a quick local test, ask them to place a plain test.txt and a tiny test.php (<?php phpinfo(); ?>) in the site root to see whether static files or the PHP pipeline are affected. Microsoft documents this error and the NTFS cause here: .

The folder which contains the website pages also needs to be allowed to the IUSR_ account as well - this can be done by right clicking on the folder and selecting properties - then click on the Security tab and work from there.
