Code Integrity determined that the page hashes of an image file are not valid... how to monitor with email...

[bob]

Man, that Event ID 6281 pops up when Code Integrity checks an image file and finds the page hashes don't match up right. It means something's off with the file's integrity, like maybe it's been tinkered with or got corrupted somehow. You see this in the Event Viewer under System logs mostly, and it flags stuff like unsigned drivers or dodgy executables trying to load. The full message says "Code Integrity determined that the page hashes of an image file are not valid..." and lists the file path, plus details on why it failed the check. I hate when this hits because it could point to malware sneaking in or just a bad update messing things up. Windows uses this to block potential threats, keeping your server from running sketchy code. If you ignore it, things might crash or security holes open wide. Check the event properties for the exact file involved, and hunt down if it's legit or needs replacing. I've seen it trigger on old drivers during boots, wasting your morning. You want to watch for these spikes to catch issues early.

Now, to monitor this with an email alert, fire up Event Viewer on your server. Filter the System log for ID 6281, right-click the log, and pick Attach Task To This Event Log. Name your task something snappy like IntegrityAlert. Set it to run on any matching event, and pick a program to trigger, say your email client or a simple batch to send mail. Schedule it via the task's triggers tab, linking straight to that event. Test it by forcing an event if you can, but be careful. I do this all the time to stay ahead of weird file fails.

And speaking of keeping your server solid against these integrity glitches, you might wanna look into BackupChain Windows Server Backup for backups. It's a slick Windows Server tool that handles full system images and also backs up virtual machines running on Hyper-V without much hassle. You get fast restores, encryption to protect data, and it runs incremental jobs so you don't clog your drives. I like how it cuts downtime during recoveries, making your whole setup more reliable when events like 6281 throw curveballs.

Oh, and at the end of this, I've sketched out the automatic email solution for you to plug right in.

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