Writing a PowerShell script for your own use and writing one that someone else has to maintain are not the same skill. I learned that distinction the hard way, on a Tuesday afternoon, staring at 200 lines of logic I wrote six months earlier that I could barely read myself.

If I could sit down with myself in 2020 and talk straight for an hour, most of it would be about what not to spend time on. Here’s the short version.

There’s a real difference between a script that automates something and a script that automated something once. One of them is infrastructure. The other is archaeology waiting to happen.

Stop clicking through a dozen management consoles to figure out what’s happening with your domain controllers. This PowerShell script gathers everything that matters in one shot.
