WDS - Auto Selecting the Image based on a template

[buckleyp]

I hope that this is the right board to post this question.

I have a WDS setup with 9 images created for different versions of Windows (2008 and 2003). I have created a number of WDS templates which will automate the selection of image and the creation of the primary partition. This works perfectly for 2008, but when pointing at a 2003 image it always displays the image selection screen and I cant get around it.

My working 2008 WDS template is

<?xml version="1.0" ?>

      </component>
   </settings>
</unattend>

and the one that does not work is identical apart from

               <InstallImage>
                  <ImageName>Windows 2003 Web x86</ImageName>
                  <ImageGroup>Windows 2003</ImageGroup>
                  <Filename>2k3webx86.wim</Filename>
               </InstallImage>

Can anyone help shed any light on this one?

Thanks in advance.
