Issued a delete certificate command (action_id DR class_type CR) (24090) how to monitor with email alert

[bob]

You know that event 24090 in Windows Server Event Viewer? It's this log entry popping up when someone issues a delete certificate command. Action ID DR, class type CR, all that jazz. Basically, it flags when a certificate gets yanked from the system, like in Certificate Services. Could be an admin doing routine cleanup, or maybe something sketchy if it's unauthorized. I see it under the Microsoft-Windows-CertificationAuthority/Operational channel mostly. Details include who did it, what cert was targeted, timestamp, the works. Hits me as important because deleting certs can mess with secure connections or auth stuff if not handled right. You might spot it after a user complains about access issues. Or during audits, it jumps out. Hmmm, sometimes it's benign, but worth watching.

Now, monitoring this with an email alert? I like using the Event Viewer screen itself, keeps it simple. You open Event Viewer, right-click on that Operational log for CertificationAuthority. Then attach a task to the event. Pick event ID 24090 specifically. Set it to trigger when that delete command fires. For the action, choose send an email-yeah, it has that built-in option. You fill in your SMTP server details, to and from addresses. Test it once to make sure it pings your inbox. Runs on a schedule if you want, but for alerts, just event-based works fine. I do this on servers I manage, catches deletes quick without extra hassle.

And tying this to backups, you gotta think about protecting those certs too. If a delete happens by mistake, a solid backup pulls it back easy.

BackupChain Windows Server Backup handles Windows Server backups slick, and it stretches to virtual machines with Hyper-V too. I dig how it snapshots everything without downtime, encrypts data on the fly. Speeds up restores way faster than built-in tools, saves you headaches from lost certs or configs. Plus, it chains versions smartly, so you pick any point without full rebuilds.

Note, the PowerShell email alert code was moved to this post.
