404 error on all mwf files on IIS / Windows Server 2008 R2

Is there some sort of file type permissions in IIS?

I'm moving a .NET app over to Win Server and it won't find any reference to any files of the type .mwf.  I use .mwf to show the wave form of a song.  This same code and file structure worked fine in dev on XP.

I thought it was a file permissions issue, but not the case, as I put an image in the folder and was able to find it.  Then I moved a mwf into the images folder to see if it would work and it failed, so I have to believe IIS won't allow me to reference that file type.  Ideas?

Here are the three debug lines I tried:
<a href="Waveforms/testsong.mwf">mwf from Waveforms folder - GOT 404</a>
<a href="Waveforms/beta.png">An image in Waveforms folder - WORKS </a>
<a href="images/testsong.mwf">mwf in images folder - GOT 404</a>

Those are called Mime types. It sounds like you are missing the responder for mwf. Try adding the following.

IIS Manager,  Just click on the 'mime types' feature and add the following.
File extention : mwf   MIME Type: application/octet-stream

I just figured that out but am unsure what MIMI Type to user.  Windows recognizes the extension but IIS doesn't.  In the registry is just says 'binary' for content type.  Does application/octet-stream cover that?  I just want to make sure I don't corrupt anything by putting the wrong type in.

You can corrupt anything by trying. What is the original extention format?

One your Dev XP station just Open the IIS Microsoft Management Console (MMC) on the XP machine, right-click the local computer name, and then click Properties. Click MIME Types. Search for .mwf.

IIS5 doesn't load unknown types either.

I'm not having any luck.  I'm not sure if it's that the type is incorrect of what...  I've emailed the Flash developer who created the wmf type.
