Hi,
 We are using Adobe Document Server 6.1 on SUN for the conversion of
 postscript files to GIF/JPG/PDF/PNG through Java API. The PNG conversion
 is successful (no errors reported by Document Server) but the output file
 cannot be read by most of the PNG viewers including Adobe SVGView3.

The only viewer I found is a Microsoft Office Picture Manager, but we
 need PNG to be viewed in Internet Explorer 5.5.

The used command is
 <commands resultOverwrite="true" errorBehavior="stop">
  <loadContent source="srcFile"/>
  <convertPSToRaster options="Press"/>
  <set target="/psd/optimizationSettings">
    <optimizationSettings>
      <PNG24Format quality="100" />
    </optimizationSettings>
  </set>
  <saveOptimized name="file:////test/3075_1234.png" appendExtension="false"/>

Do you have any suggestions regarding this issue?
 Regards,
   Oleg.

Do your source EPS have transparency? I found some articles that IE doesn't fully support PNG24--especially transparency.

Try converting a simple EPS to PNG and seeing if that works in IE.

If Photoshop and Picture Manager can open the PNGs then the problem is most likely that the other viewers don't yet support all the features of PNG24.
