Website runtime error

Hi,

     I created a copy of the wwwroot folder(which currently has the website information) and renamed it to test_wwwroot and the path locations are c:\Inetpub\wwwroot & c:\Inetpub\test_wwwroot respectively. But now when i try to run the newly created copy which is test_wwwroot it is throwing me the error as below. Can someone guide me if there is any step that i missed or is there any other process to make a copy of the functioning website to use it as dev/test environment through the same IIS manager. Any help would be greatly appreciated.

Server Error in '/' Application.

Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".











Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.
