Digital Resume Creation


After creating this site you are on, I decided to document exactly how I did it and the issues I had to troubleshoot. I have included the files I modified and any other tweaks necessary to make my site work. Please reach out to me if you need more information.

AD Cloning Scripts


When working with a client recently, I was asked to create a DEV and TEST environment for them that mirrored their Production AD environment. I start searching to find PowerShell scripts that would do that. I could not find a single end-to-end script that did it. I was a bit surprised and set out to create my own. This is the result of several hundred hours of research, scripting, and testing.

  • 3 different scripts for getting source objects, creating the new domain, and keeping the source and target domains in sync.
  • All scripts have customizeable variable sections at the top where necessary.
  • The scripts avoid hard pathing and all use relative paths.
  • The whole process will take a LONG time to run. Several hours at least. Especially for a large environment.
  • Tested only on Windows Server 2019 with Exchange 2019. Should work on newer or older Server OSes and Exchange with a small bit of tweaking.
  • This is a living project, so feedback is always welcome.
