Do not modify the "Execute On" setting for builtin Active Roles Scheduled tasks.
If this is done accidentally, then revert them to the default setting.
The
Update Services To ExecuteOn Scheduled Task is the only scheduled task that should be linked to one specific Active Roles service instance. All other scheduled tasks should be set to execute on "All servers".
NOTE: If a scheduled task has been updated incorrectly, see
this resource for information on changing it back to the default setting.
