We’ve created a windows authenticated sub directory on our web server, however, intermittently when we go there (once logged in as an authenticated user – member of a authenticated group) we get the following error:
Module IIS Web Core
Notification BeginRequest
Handler Not yet determined
Error Code 0x80070005
Config Error Cannot read configuration file due to insufficient permissions
Config File \\?\C:\Inetpub\wwwroot\admin\web.config
Requested URL http://testsite.dev:80/admin
Physical Path C:\Inetpub\wwwroot\testsite\admin
Logon Method Not yet determined
Logon User Not yet determined
The odd thing is once we see this error, hit F5 or refresh and the error goes away, only to reappear a short time later. Very frustrating!!
I have done extensive searches online, but can find nothing. We may also create other sub dirs allowing the same “group” to have access, so this needs to work across all these subs without having to relog in.
We are using IIS7. I’ve found guides that state for IIS7 ( http://kenno.wordpress.com/2008/10/23/iis7-cannot-read-configuration-file-due-to-insufficient-permissions/ ) but when I do this it seems to then make the directory accessible to all which is clearly not required.
Following my own advice and knowing nothing about the problem, I give you an answer to be accepted or improved upon:
See Configuring Security at IIS.net.
