Thanks, that was an interesting thread. I posted there as well.
In my testing, policies do run the next time a machine powers on if it's off at the scheduled time.
I had mine set to weekly/monthly vs custom but the reason I didn't like this is my machines are all off at 6pm, and I don't want to wake them up. I also don't want all machines running inventory at startup (because the 6pm was missed).
This was happening and although it's not a memory hog, with everything else happening during a computer startup/login, I just prefer to choose a time during the day and if a machine is off or asleep, it will run the next time it powers on.
It's just strange every so often I come across a machine that hasn't ran a delta or full in way too long (so far usually a laptop that is off and on randomly, but on long enough a delta or full cound run) and can't figure out why.
