@skotteru I use Active Directory and I deployed a whole lot of Win8.1 machines recently and I don’t sysprep. I maintain one image for each model of PC in my building - this is to keep my images lean and mean and fast - fast to deploy - fast to boot. (5 minute deployment time for 40GB image).
You upload when the client is not on the domain, and use the fog client (Legacy and New works on 8.1) to join the domain after imaging.
But you will find lots of mixed opinions on how to do it.
You know what I say, now? Do what floats your boat, I don’t care lol. I’m maintaining an image per model!
