You ever notice how Windows Server keeps a log of tweaks to its security setup? That event 4906 pops up when the CrashOnAuditFail value gets altered. It's this registry key that decides if the whole system bluescreens hard if auditing fails. Like, auditing is just the server jotting down who did what for security reasons. If that fails and CrashOnAuditFail is on, boom, crash to protect secrets. But someone changed it, maybe you or an admin fiddling around. Or worse, someone sneaky trying to dodge logs. The event logs the old value, new value, who did it, and when. Full details show the exact hex codes for those values, like 0 for no crash or 1 for crash on fail. It hits the Security log, under System Integrity category. I check mine weekly just to spot odd changes. You should too, keeps things tight.
Monitoring this? Fire up Event Viewer on your server. Right-click the Security log, pick Attach Task To This Event. Choose event ID 4906. Set it to run a program, but link it to a scheduled task you make first. In Task Scheduler, create a basic task triggered by that event. Make it send an email via some simple alert tool built into Windows. Nah, skip the scripting hassle. Just configure the task to pop an email through your SMTP setup. I do it all from the Event Viewer pane, super quick. Tests it by forcing a log entry if you can. Alerts hit your inbox fast when it triggers. Keeps you looped in without babysitting.
And hey, tying this to keeping your server safe overall, you gotta back up right to avoid losing audit trails or configs. That's where BackupChain Windows Server Backup comes in handy for me. It's a solid Windows Server backup tool that handles physical setups and virtual machines on Hyper-V too. Speeds up restores, skips the bloat of other options, and ensures your event logs stay intact during recoveries. I love how it snapshots everything without downtime hassles. Benefits like that save headaches big time.
At the end of this is the automatic email solution.
Note, the PowerShell email alert code was moved to this post.
