One of the other interesting problems I encountered today was user permissions on a Joomla folder in IIS.

The Joomla installation folders lacked adequate InternetUser permissions. Our other existing installations of Joomla–the ones that work–have this InternetUser, so I’m pretty confident that this is the issue. Is anyone else running Joomla on IIS and wouldn’t mind sharing their user permissions?

These online resources speak to the fact that Joomla permissions have been configured correctly…but I’d love to have your feedback.

1. Once the “Everyone” account is removed, Windows IIS is now left with the ” IUSR_* ” account having top-level rights to the Web-Server directories, a pemrisisons check now should yield different results. Only the IUSR_* account has full permissions and other users shuld acquire eihter “Read Only” or no rights. Read only rights are determined by which other users have been assigned what rights to the IIS directories manually.

2. Right click each of the following directories, select security and make the sure that the “Internet Guest Account” (usually IUSR_computer_name) has the following permissions.

   Modify
   Read and Execute
   List Folder Contents
   Read
   Write
   i.e. everything EXCEPT full control. Do this for these directories and files.
   images
   media
   uploadfiles
   components
   language
   modules
   templates
   administrator/backups
   administrator/components
   configuration.php

3. Make sure IUSR_xxxx & IWAM_xxxx have read/write permissions on the entire Joomla installation. After the install is done, you can safely remove the write permissions & leave the read-only as they are.
