# General access denied error

To resolve this problem, follow these steps:

1. In a text editor, open the ApplicationHost.config file.
   Note The ApplicationHost.config file is located in the following folder:
   %SystemRoot%\system32\inetsrv\config
2. Locate the ipSecurity XML element, and then set the value of the allowUnlisted property to true.

After you follow these steps, IIS accepts requests from any IP address that does not appear in the list of IP addresses under the ipSecurity XML element.

Note The security level of the server that is running IIS may be decreased when you enable IIS to accept requests from any IP address.
