IIS will prevent many file types form being launched via Internet Explorer unless it is explicitly told to allow them. In this case you may need to add a Mime Header file type to the UniversitySite website.
- Right click on the UniversitySite website in IIS and choose properties.
- Select the HTTP Headers tab
- Click the File Types button under the MIME Map section
- Click the New Type button
- Enter nrl or drf or scl or whatever file type you need to allow through IIS in the Associated Extension and specify “text/plain” for the Content type(MIME) field
- OK your way out
