Someone wake me up or tell me this isn't a sick joke. ArcGIS Server Standard Enterprise geoprocessing licensing does not seem to support something as basic as calculating a distance between two features. Is there really not a way to do this?
Thank you for the confirmation Kevin. Bruce, thank you also for the reminder that the geometry service does have a measure method which I may be able to use in the future for small tasks. For my current task I don't think it would be feasible to send hundreds of millions of requests to the geometry service one at a time, so I have written a REST service that will not use ArcGIS Server and maybe in the future we will purchase server advanced.
