⚙️ PowerShell Automation
18 PowerShell scripts for network discovery, system health checks, and security auditing. If I do something by hand twice, it becomes a script.
Overview
A toolkit for the tasks that come up over and over in MSP work: network discovery, system health checks, storage and security troubleshooting. Every script follows the same conventions — standard param blocks, CSV export, colored output — so they're easy to reuse.
The centerpiece is a network scanner using async pinging and multi-threaded runspaces to sweep a subnet fast. It does port scanning, subnet auto-detection, ARP-based MAC lookup, and vendor resolution via the macvendors.com API. Around it sits a broader set covering storage, system health, networking, and security auditing.
Technologies Used
- PowerShell
- Windows Management Instrumentation (WMI/CIM)
- Runspaces & Multi-Threading
- ARP / MAC Address Resolution
- Git & GitHub
Highlights
- Built an async, multi-threaded network scanner with configurable port scanning and subnet auto-detection.
- Added ARP-based MAC lookup with manufacturer resolution via macvendors.com.
- Wrote 18 troubleshooting scripts spanning storage, system health, networking, and security auditing.
- Standardized every script with consistent param blocks, CSV export, and colored console output.
- Added elapsed-time reporting so long-running scans are easy to track.
- Wrote a driver-inventory script using the Windows Update Agent COM API and PnP driver data to flag outdated drivers.
Challenges
- Getting runspace pools to scale cleanly without overwhelming the network or the host machine.
- Handling inconsistent WMI/CIM responses across different Windows versions.
- Keeping script output format consistent as the toolkit grew from a handful of scripts to eighteen.
What I Learned
Runspaces versus simple loops makes an enormous difference for anything touching the network. And once a toolkit passes a handful of scripts, consistent conventions save more time than any single optimization.
