ASP.NET WebForms: Why can't I download certain files that I've uploaded through my application?

I have a simple asp:FileUpload control that saves a file to the server. It saves the file to disk then creates a path reference to it in the database. We display these files in a DataGrid using this markup:

<ItemTemplate>
    <a href='<%# MyApp.Global_asax.UploadPath + DataBinder.Eval(Container.DataItem, "FolderName") + "/" +  DataBinder.Eval(Container.DataItem, "FileName") %>' target="_blank">
        <%# DataBinder.Eval(Container.DataItem, "FileName") %>
    </a>
</ItemTemplate>

So, as you can see, it's nothing special. However, trying to download some files results in this message in IE9:

The page cannot be found
The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.

I get a similar message in FireFox.

So far, this is happening only with .DOTM files. I thought it could be the file name, so I changed the name to something simple like xxx.dotm, but this still doesn't download. When I change the extension to TXT so it's xxx.txt, though, I am able to download the file just fine.

Is anyone able to give me an idea as to what's going on here?

You need to add the MIME type in IIS for that file extension.

For IIS 6.0:
