I'm on IIS6 and asp.net 3.5 SP1.
I decided that my asp.net web application should have a dedicated application pool and a dedicated identity, because this identity is granted access to a sensitive file share that the web application uses. The web application uses integrated windows authentication for the incoming users, and my problem is that when the application pool is set to a dedicated identity, all incoming users fail to authenticate, i.e. the login box (from internet explorer) re-appears after the user submits his password. This problem does not occur when the application pool is set to the NETWORK SERVICE identity.
The dedicated identity has been granted access to the machine's IIS_WPG group and I have tried the following command:
aspnet_regiis.exe -GA myDomain\myDedicatedIdentity
But still no luck. Any suggestions? Any privileges that I forgot to grant to this identity?
