HTTP Error 404.3 - Not Found

I use asp.net in windows vista. IIS7 is setup there.
In small application I want to display pdf or djvu files. When I click
link to pdf file I do not have any problem. When I click djvu file I get
responce
HTTP Error 404.3 - Not Found
Description: The page you are requesting cannot be served because of the
Multipurpose Internet Mail Extensions (MIME) map policy that is
configured on the Web server. The page you requested has a file name
extension that is not recognized, and is not allowed

Because design of IIS changed it is not clear how I can add djvu to MIME,
what is difference between djvu and pdf. I do not see pdf in MIME also,
but I can seepdf on the client site.
Thank you, Aleks Kleyn
