This example gets an administrative token and then starts the geometry service. It is an easy script to test, since all ArcGIS Server sites include a geometry service named Geometry that is stopped by default. Also, this request only needs two parameters: the token and the response format.
Starting a service requires administrative privileges, so a user name and password with administrator privileges must be supplied when running this script.
