If a Remote Job has been configured to run several times it may be important to select the Filter option Don't execute again on a computer where the action was already executed.
This Filter setting is useful if you want to install a specific software on numerous computers including those rarely available on the network (e.g. laptops). It will permit you to schedule many attempts on your Target Computers and request RemoteExec to not try to install the software if it was previously done successfully.
