Structured deep-dives on Active Directory, PowerShell, and infrastructure that has to keep running.
Written for engineers who want to know why something broke, not just which command fixes it — a growing library of guides across identity, automation, and homelab infrastructure.

Learn Active Directory from the ground up
The full 13-part concept series — forests and domains through Kerberos, replication, and trusts, in the order they actually build on each other.
Part 1: What is Active Directory? →Diagnose a live incident
Troubleshooting guides organised by the literal error text — KRB_AP_ERR_SKEW, DFSR backlog, stale DNS after a DC decommission — so you can search the symptom, not the theory.
Browse Troubleshooting →Stand up your own lab
Proxmox, chrony/NTP, and the same automation patterns used in production — scaled down to a single box at home.

Active Directory — From the Ground Up
A complete 13-part path from first principles to production-grade AD — forests and domains, FSMO roles, replication, Kerberos, trusts, GPO, and the failure modes of each.
About me
Built on curiosity. I spend my days keeping identity and infrastructure running — Active Directory, Windows platforms, and the automation that holds them together — and my evenings breaking things in the homelab to understand why they work. Everything here is written the way I wish documentation was: from first principles, with the failure modes included.
