George - Make sure your custom error message for the .shtml pages is larger than 512 bytes. IE will display its own 404 page if the server's is less than half a K. Once its over that limit, IE will do the rigth thing and display the server 404. There is also some advanced option tab in the IE preferences that has something to do with 404's, although I can't think of it offhand .djc.
