I asked a similar question to the bloodhound folks, hoping there were some scripts not just to create the domain, but populate it to scale with users and computers. Apparently @clong has one https://github.com/clong/DetectionLab that uses vagrant to create an AD server, so a good place to start.

Thanks, that's what I'm looking for is to have simulated data within. I found this as well but I think it's more for just getting the environment up quickly: https://github.com/outflanknl/Invoke-ADLabDeployer
