Have you confirmed, by using the Task Scheudler itself, that the "wake computer up" actually works on that specific computer. I'd check the basics first before trying to script it via KiXtart. The wake-up functionality might be hardware-dependent and also not work with all system states. I'm also not sure whather JT.EXE will support all advanced functions that the Task Scheduler provides.
