A Trigger must be assigned to a Client Task for it to be executed. To defining a Trigger, select the Target computers or groups on which a Client task should be executed. With your target(s) selected, set the trigger conditions to execute the task at a particular time or event. Additionally, you can use Advanced settings - Throttling to further fine-tune the Trigger, if required.
Enter basic information about the Trigger in the Description field and then click Target.
The Target window allows you to specify the clients (individual computers or groups) that are the recipients of this task. Click Add Targets to display all Static and Dynamic Groups and their members.
Select clients, click OK and proceed to the Trigger section.
Trigger - Determines what event triggers the task.
NOTE: For more information about triggers, proceed to the Triggers chapter.
Advanced settings - Throttling - Throttling is used to restrict a task from being executed if a task is triggered by a frequently occurring event, for example the Event Log Trigger or the Joined Dynamic Group Trigger (see above). For more information, see the Throttling chapter.
Click Finish when you have defined the recipients of this task and the triggers that execute the task.
