Mode browse works but mode map and wms server do not?

[Miller Joseph]

Problem:
Mapserver 4.6 on IIS 6 (Windows 2003 Server)works in browse mode but
when I need it to stream png files, either in mode=map or as a wms
server, the browser only shows a broken link.  In addition, the streamed
output jpg files look extremely distorted, but it's definitely not a
projection issue.  (BTW, I had exactly the same issues with Apache on
this machine)

I have built mapserver 4.6 with the following capabilities:     
   
MapServer version 4.6.0 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=SVG
SUPPORTS=P
ROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT
SUPPORTS=WFS_SERVE
R SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=FASTCGI INPUT=SDE
INPUT=OGR I
NPUT=GDAL INPUT=SHAPEFILE DEBUG=MSDEBUG


My map file is below(the urls,username, and password have been altered):

Any ideas?
