  • Applies to:
  • Plesk 9.x for Windows


Parallels Plesk Panel is installed on the container using Virtuozzo template.
Sitepreview does not work for any websites on the server. But direct access to the domains on this server works normally. Browser displays the error:
"HTTP Error 401.3 - Unauthorized".
You do not have permission to view this directory or page because of the access control list (ACL) configuration or encryption settings for this resource on the Web server. 


Default IIS anonymous user (IUSR) is used for previewing websites. If Parallels Plesk Panel is installed through the template, this user is not added to the psaserv group. So there is no permission to access to the sitepreview library.


Default IIS anonymous user (IUSR)  can be added to the psaserv group manually.
> net localgroup "psaserv" "IUSR" /add

Permissions for IUSR user are strongly cached. For applying changes it is necessary to reboot the container.

To see if user IUSR is already added to the group 'psaserv', execute the following command.
> net localgroup psaserv
