You have a Web site that is hosted on Internet Information Services (IIS) 7.5

This problem occurs because the ApplicationHost.config file has a duplicate entry for the following code.

To resolve this problem,

In the ApplicationHost.config file, delete the duplicate entry for the authorization rule. To do this, follow these steps:

Click Start, type Notepad in the Start Search box, right-click Notepad, and then click Run as administrator.

Note If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
On the File menu, click Open, type %windir%\System32\inetsrv\config\applicationHost.config in the File name box, and then click Open.
In the ApplicationHost.config file, delete the duplicate entry that resembles the following code.

Hope This will solve your problem...

Regards,
Vishal
