Terraserver WMS

[Chip Taylor]

I am trying to create a group of layers using WMS on Microsoft Terraserver.

I run MapServer on an IIS6 web site as a CGI app.
I cannot seem to get this to work correctly.  Here is my Mapfile (at least
the pertinent sections:


# This is the site map file
NAME "sitemap"
UNITS DD
EXTENT -127.00 43.00 -115.00 50.00
SIZE 475 475
IMAGECOLOR 189 202 222
IMAGETYPE GIF

SHAPEPATH "../Shape_Files"
FONTSET "../fontset.txt"

Here is the error I get when I try to render the map:

msDrawMap(): WMS connection error. Failed to draw WMS layer named
'ortho-18'. This most likely happened because the remote WMS server returned
an invalid image, and XML exception or another unexpected result in response
to the GetMap request. Also check and make sure that the layer's connection
URL is valid. 
msDrawRaster(): Image handling error. Unrecognized or unsupported image
format
drawEPP(): Image handling error. EPPL7 support is not available.

What am I doing wrong?  Thanks in advance for your help.
