If you are using Windows Server 2008 or Windows 2012 and a MIME type already exists
on the web server that is repeated in the web.config file, you will
receive an error when you access any launch page in the site. To correct this condition,
you must delete the duplicate reference in the web.config file:
-
Navigate to the site that contains the conflict.
-
Open the web.config file in a text editor.
-
Locate the conflicting file extension and delete the corresponding line.
For example, if IIS generates an error for the
.mdp file
extension, delete the following line in the
web.config
file:
<mimMap fileExtension=“.mdp”
mimType=“application/octet-stream” />Note: Ensure that you delete the
entire line and remove any blank spaces.
-
Save and close the file.
-
Access the launch page again and ensure that you no longer receive the error
message.
