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 '.*'"
This error usually occurs when using IIS 7/7.5 because the wildcard symbol (.*) is not used in later versions of IIS.
It means that there is a ".*" entry in the MIME types.
Fix this issue by removing the MIME type entry ".*", or replacing it with ".".
- Open the IIS manager.
- Go to the OfficeScan web site.
- Open MIME Types.
- Remove the MIME Type entry ".*", or replace it with "." if you want to include a wildcard.
- Restart the OfficeScan web site.
