Upgrade time job status is set to: Aborted. Error Message: The administration service job definition 'solution-deployment-nintexworkflow2013core.wsp-0' (id ce24cae5-8a2b-4383-b140-2d3203d3b6f4) was not executed because the administration service on this server is not started. This job definition can be run manually using 'stsadm -o execadmsvcjobs'.   

One or more errors were detected. Please scroll up for details.

Where do I find the administration service on the server? From the list of services I did not see it listed.
