How to configure an Agent Policy to run a patch task on boot if the schedule is missed
To create an Agent Policy go in New > Agent Policy Create or Modify existing agent policy
To modify an existing Agent Policy click on the button just under Home and Agent Policies
Configure Patch Task Schedule to "Run on boot if scheduler missed"
You configure agent patch tasks on the Patch tab. You can edit an existing patch task, or you can create a new task by clicking Add a Patch Task.
Select the check box labeled "Run on boot if scheduler missed"
If a scheduled task is missed while a target machine is powered off, this option enables you to force the task to automatically run whenever the machine is restarted. The task will run immediately unless you enable the Delay after boot (minutes) check box, in which case the execution will be delayed by the specified number of minutes.
Assign the policy to agent machines using Install/Reinstall with Policy or Assign Policy in Machine View or Scan View
