Export a backup copy of your IIS 7.0 configuration

To export a backup copy of your IIS 7.0 configuration on a Windows 2008 Server:

Open Server Manager

Expand Roles – Web Server (IIS) – Internet Information Services (IIS) Manager

Highlight the web server name

From the Management category, double click Shared Configuration

Under Actions, select Export Configuration. Accept or change the default export path of C:\Windows\system32\inetsrv\config\export

Click the Connect As button, and enter administrative credentials. If the server is a domain member, you may need to enter your credentials in the format domain\username or username@domain.com

Enter the encryption keys password twice and press OK

You should now have three files in the C:\Windows\system32\inetsrv\config\export directory: administration.config, applicationHost.config, and configEncKey.key. Save the files in a safe place.
