What is wrong with this picture?

Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
content-disposition: attachment; filename=Hill%20Country%20water%20issues[1].ppt
Content-Type: application/unknown

IIS servers don't come provisioned with the .ppt extension mapped to application/vnd.ms-powerpoint? Microsoft server? Microsoft application?

What hope can there be for authoritative metadata?

My Firefox browser figures it out just fine, and launches Open Office. Presumably FF went through all this first, just to determine it to be application/octet-stream; then ran a further sniffer to identify it as a Power Point.
