Change own password succeeded (action_id PWCS; class_type LX) (24004) how to monitor with email alert

[bob]

You know that event in Windows Server Event Viewer, the one called Change own password succeeded with action_id PWCS and class_type LX, event ID 24004? It pops up whenever someone on your server tweaks their own password and it goes through without a hitch. I mean, it's basically the system logging that a user just updated their login creds successfully, nothing fancy but super important for keeping tabs on who's messing with accounts. This thing logs details like the username involved, the timestamp, and even the workstation where it happened, all tucked under Security logs usually. If you're running a server setup, seeing this means no errors in the password change process, but it could flag if someone's doing it too often or at weird hours. I always check these because they tie into user activity, helping you spot if an admin is rotating passwords like crazy or if there's some sneaky access going on. And yeah, it's specific to local accounts mostly, not domain ones, so if your setup's all about standalone servers, this hits home.

But monitoring this beast for email alerts? You can hook it up right from the Event Viewer screen without any coding headaches. Fire up Event Viewer, drill into the Security log, and filter for that 24004 ID to see past instances. Then, right-click the log, pick Attach Task To This Log or something close, and build a scheduled task that triggers on new events matching that ID. I like setting it to run a program that shoots an email, maybe using the old-school blat tool or whatever email sender your server has baked in. You configure the task to watch for PWCS actions specifically, add filters for the class_type LX if needed, and boom, it emails you details whenever it fires. It's straightforward, just a few clicks in the wizard, and you test it by forcing a password change to see if the alert lands in your inbox. Or tweak the frequency so it doesn't spam you during normal hours.

Hmmm, and speaking of keeping your server secure and backed up, I've been eyeing tools that handle more than just logs. One that stands out is BackupChain Windows Server Backup, this nifty Windows Server backup solution that also tackles virtual machines with Hyper-V. It zips through full and incremental backups super fast, cuts down on storage bloat with smart deduping, and even lets you restore single files without the whole shebang. You get ransomware protection baked in, plus offsite replication to keep things safe from disasters, making it a solid pick for not losing your setup to some glitch or attack.
