Hi Jared,
Can I step back a bit here and make sure everyone is talking the same thing.
Are you talking about tasks you have scheduled locally on the client or are you talking about tasks you have scheduled centrally on the server. I don't see that you specifically identify reading back in this thread.
If you are scheduling locally, have you instead tried scheduling centrally? A centrally scheduled task shouldn't be slipping anymore (it used to but that is what I remember changing). Even in a very large environment it should be possible for it to contact each device that is online within the window you need. Also if you have a pretty frequent policy check interval and have it setup as a policy supported push then you have the belt and braces of policies picking it up. Locally scheduled tasks may seem the obvious thing to use but they weren't actually designed to do specifically what you are trying to do here even if it seems like they should have been. Would the alternative I've suggested work, or is this actually what you are struggling with?
