If you recall my post from six months ago, I released a PowerShell script called Coerchck for iterating through /24 subnets to list all local administrator accounts on Windows machines.
I finally released version 0.2 today after many hours of delayed work. Sadly, however, my home-brew subnet calculator is a still a little rough around the edges (a fact that weighs its shame heavily upon me, I assure you). Nevertheless, I wanted this tool available to not only myself but other security professionals who may find themselves in need of such a script. To that end I found a concise little function on TechNet with a license that would allow it to be added to my script.
