ASP.NET IIS - Error: 0x80070005 Access is denied.

Hey...

I was trying to run a website from my IIS. The same website is working very well when i run through my Visual studio. The error shown when i browse the site through IIS is as follows:

Server Application Unavailable

The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request.

Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.

So I checked the event log and there were three logs created on the same time when i run browsed the site:

1.
aspnet_wp.exe (PID: 6024) stopped unexpectedly.

Solution:
I read the forums and the solution worked for me is I gave permission for ASPNET account for GAC folder with the following syntax in command prompt:

Syntax: CACLS c:\windows\assembly /e /t /p {MachineName}\ASPNET:R

to be on safer side, For ASPNET account, i have given read permission for the project folder too.

now the issue is fixed.
