Scripting

I have enabled all workstations (300+ count) to turn on at 10:30pm daily via the BIOS Auto On setting. I also am using KACE's auto shutdown script to power off all these workstations at 2am. I have a scheduled task for this to run daily as well. Unfortunately, this task has a mind of its own and decides when it wants to run. Some days I look at my inventory and none of the machines shut down and some days it runs perfectly. It's sporatic.

Does anyone have any input on what may cause the shutdown not to initialize properly? No other tasks are ran at this point. Right now it's just a power on at night and a power off in the morning.

Thanks.
