You can verify that your ms4w suppports DNG data by executing the 
following at the commandline:
- execute: /ms4w/setenv.bat
- execute: ogrinfo --formats
- look for a '"DGN" (read/write)' line
- now try a shp2img command with your mapfile (see 
- make sure your dng layer is in the same projection as your other data
    - possibly remove all other layers. projection objects, and set the 
map's EXTENT to that DNG layer, and then retry shp2img

Mapfile example: http://mapserver.gis.umn.edu/docs/reference/vector_data/dgn

Here's more reading on how OGR support DGN files: 

have fun.
