That was sad. I've read through the MS Press book, the MS It academy materials (provided by WGU), Darril Gibson's college textbook, and even the Syngress book, though it was geared toward R1. All that, lots of labbing, reading the IPD guides, and trouncing selftestsoftware's 70-647 exams, and I still walked out with a fail.
Long story short, I spent a lot of my prep time focusing on the functional levels of AD (actually built a forest on 2000, then migrated in stages to 2003, then 200

, the ins and outs of autonomy & isolation in AD, group policy precedence, and domain restructuring. Of those, group policy was the only one that came up frequently. I honestly felt like I studied for a completely different test.
So I'm going to give it another go sometime in November. I think this time I'm pretty much going to stick to TechNet as my primary resource. I'm entertaining the thought of ponying up for LabSim if I can get the student rate, but wanted to ask if anyone's used it for 70-647 before I shell money out of pocket for it.
