Q&A Monday: IIS 7.5 Error 401.3

Question:

I’m trying to test my ASP.Net website and I keep getting this 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.

I tested the site both from the IP address, as I have locally on that server to make sure it wasn’t something else.  I have the following users on the website application folder, with full read/write permissions:

  • NETWORK SERVICE, IIS_IUSRS, SYSTEM, Administrators, Helpdesk, PJordon (my account)

Is there something I am missing, to get me able to view the site?  Could I have set up something wrong?

Answer:

IIS7 created another user account which may be the cause of these problems, IUSR.  Check to make sure this user has read access to the folder and files you are trying to access.  You can do this by checking the security tab and seeing if this user in that list.  If not add them, and you should be on your way.
