I'm using the PrintTask in my SilverLight application. When I disable the servicesDirectory, the printTask returns error 403 : "Services Directory has been disabled". In Fiddler, it looks like it tries to get to arcgisjobs but because it is disabled, it returns an error. I thought to use https://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer but I have my own template for printing. I want the servicesDirectory to stay disabled for security reasons but I want the printTask as well.
It's easy to reproduce, simple disable the servicesDirectory with http://server_name/arcgis/rest/admin, uncheck Services Directory Enabled checkbox and try to print something from that ArcGIS Server. Any idea will be very helpful!
