Deployment jobs on certain known/managed endpoints while in automation never run and the job status changes to "replicated"
DS 8.x
In one scenario, Deployment jobs are not running on certain managed endpoints because the console is holding on to a stale/incorrect agent record information.
Deleted the endpoint's entry in the console (Manage > Computers > search for endpoint you want to run the deployment task on) before booting it to automation.
NOTE: There may be other causes to this behavior but this is one scenario that has been seen.
