The following error message appears when accessing the OfficeScan (OSCE) server web console:
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid
Config error: "Cannot add duplicate collection entry of type 'mimeMap' with unique ket attribute 'fileExtension' set to '.*'"
If the config error is the same as the one indicated above, it means that there is a ".*" entry on the MIME types.
This error usually occurs when using IIS 7/7.5 because the wildcard symbol (.*) is not used in later versions of IIS.
