Iis cannot read configuration file web.config

I'm running IIS 7. I made new IIS website and pointed it at the path. When I added the permissions it still didn't work. It only started working when I gave the following permissions to the 'Users' group and inheritance cascaded the permissions to web.

Probably should have applied it just to the web. We had a website running with a specific identity in the apppool, only after giving that user read access to the folder containing the web. We tracked this down after adding the 'everyone' user with read and everything worked fine. For me the error turned up during Debugging on my local machine and turned out to be related to the base web. NET Framework when compiling the website.

I had this error message that turned out to be due to my physical folder being located on a network drive as opposed to the local drive. It seems the permissions on such drives by default can be different. For example, while the local drive location gave permission to the users of the local computer, the network location did not.

Further, the accepted answer does not work for such a case. The local users or IIS users were not an available to assign permissions to. The solution was to move the physical folder to the local drive. I had the same issue and after doing all the stuff written here as answers, it still reproduced.
