The standard feature analysis tools available in the Portal for ArcGIS website (e.g., in Map Viewer) create new hosted feature layers as their output. This functionality requires a federated ArcGIS GIS Server to be designated as the organization's hosting server. The hosting server provides the necessary data storage and processing environment for these outputs. Even if the SpatialAnalysisTools geoprocessing service is running on a federated server, if no server is configured as the hosting server, the analysis tools will be unavailable to all users in the portal, as there is no designated location to store the results.

A. The Creator user type is a prerequisite for using analysis tools, not the cause of the problem. A user must be a Creator (or GIS Professional) with appropriate role privileges to perform analysis.

C. The question explicitly states the service is "verified to be running." While a restart can resolve transient issues, it is a troubleshooting step, not the root configuration cause for the tools being unavailable.

D. SpatialAnalysisTools is a geoprocessing service, not a data layer. It is published as a service to a federated server and cannot be published as a hosted layer.

1. Esri ArcGIS Enterprise Documentation. "Configure a hosting server." ArcGIS Enterprise 11.1 Documentation. This document states

"A hosting server is required to... Perform feature analysis in Map Viewer and the portal website... The analysis tools create hosted feature layers as their output. Therefore

a hosting server is required to store the analysis results."

2. Esri ArcGIS Enterprise Documentation. "Organization roles." ArcGIS Enterprise 11.1 Documentation. Under the "Privileges" section

the table shows that the "Spatial analysis" privilege (required for using analysis tools) is available to roles like Publisher

which are assigned to Creator user types. This confirms that the user type is an enabler

not a blocker.

3. Esri ArcGIS Enterprise Documentation. "What is a hosting server?" ArcGIS Enterprise 11.1 Documentation. This page clarifies

"The hosting server hosts these layers and the data they contain

and it also keeps track of who has access to the layers." This reinforces the central role of the hosting server in managing content created through portal functions like analysis.
