HTTP Error 500.19 - Internal Server Error while attempt to browse web application

Question

On my attempt to access my site from IIS, i am getting following error.

HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.

Module: IIS Web Core Notification: Unknown Handler: Not yet determinedError Code Error Code: 0x80070005 Config Error: Cannot read configuration file due to insufficient permissions Logon Method:Not yet determined Logon User:Not yet determined

I am not sure what to do. I have already given full control to mycomputerName\ISS_IUSRS for applicationHost file in C:\Windows\System32\inetsrv\config. Also, I have given full control to mycomputerName\ISS_IUSRS for applicationHost file to my solution folder and web.config file. However, when I click on my application from IIS and attempt to browse it by clicking on manage Application\browse, I am still getting this error.

If anyone could help me, that would greatly be appreciated, Thanks

This problem mostly occurs when the IIS application don't have the permission to the read the application configuration files. IIS application uses the IIS_IUSRS user to read the Web application.

The IIS_IUSRS user will have default read and execute access for the folder C:\inetpub\wwwroot\ once when you install the IIS. Kindly copy your Web Application folder to the above mentioned directory and give the read access or full control(if the IIS_IUSRS don't have the read and execute permission) for the IIS_IUSRS to your application folder.
