downloading from image server

PaigeBaldassaro — Tue, 11 Oct 2011 19:40:54 GMT

We are running ArcGIS Server 10.0 on a Windows 7 machine. I've configured the arcgisoutput virtual directly correctly (images are getting placed in there). However, whenever I try to download from ArcMap, the download status always goes to "failed". With no information as to why.

Anyone have an idea what is happening, or can point me where to look for errors?

Be sure that you have authorized under the MIME settings in IIS to allow those raster types to be recognized. It is discussed here. Without those settings, the files will fail during the download.

I set up the MIME. Even set up .* application/octet-stream in case I was missing one. Still didn't seem to work.

When troubleshooting the arcgisoutput virtual directories you can try a couple of things:

If an image is actually getting generated and placed in the arcgisoutput folder, try viewing it directly in your browser using the URL configured for that virtual directory.

eg: http://<servername>/arcgisoutput/_ags_map54112cdc0d734f2b8dcfeeeb2e78405b.png
*note: arcgisouput images will only be generated for non-cached services

This will test your virtual directory configuration and make sure IIS is working properly.

The next step (assuming you don't find a problem with IIS) will be to use something like fiddler (http://www.fiddler2.com/fiddler2/version.asp) to watch the connections that ArcMap attempts when trying to access the arcgisoutput folder.

Start fiddler, then start ArcMap and watch the conversation in fiddler as ArcMap attempts to load the images from the arcgisoutput folder. Using fiddler, you can diagnose the http connection to IIS that is failing by copying each failed URL into your browser and working to diagnose the problems it reports.

Hope these tips helped!
