Remove-AuthRedirect Exchange cmdlet issued (25701) how to monitor with email alert

[bob]

You know that event in Windows Server Event Viewer, the one labeled "Remove-AuthRedirect Exchange cmdlet issued" with ID 25701? It pops up when someone runs a command to yank away those authentication redirects in Exchange. Basically, it means a user or admin just issued that Remove-AuthRedirect cmdlet, which strips out any redirects that were forcing logins to bounce to another spot. I see it trigger in logs when folks tweak email auth setups, maybe to fix a glitch or tighten security without the extra hops. And it logs the details like who did it, from what machine, and the exact time, all tucked into the Security or Application log under Exchange categories. Hmmm, sometimes it flags if it's an unexpected run, hinting at possible meddling if you're not careful.

But you want to keep an eye on it, right? Fire up Event Viewer on your server. Scroll to the Windows Logs, pick Security or wherever Exchange stuff hides. Right-click the log, hit Filter Current Log, and punch in 25701 for the event ID. That narrows it down quick. Now, to get alerts, you set a scheduled task right from there. In Event Viewer, find your filtered events, right-click one, and choose Attach Task To This Event. Name it something snappy like AuthRedirect Alert. Tell it to run a program that shoots an email-maybe use the built-in SendMail or whatever your setup has. Set the trigger to whenever 25701 fires. I do this all the time; it wakes me up if something fishy happens at night.

Or, if you tweak the task properties, make it email you straight away with the event details copied in. Just point it to your SMTP server and your address. Keeps things simple without digging into code. You test it by forcing the event if you can, but watch out, don't break production.

That covers the basics for watching those 25701 hits. And speaking of keeping your server humming without surprises, I've been messing with BackupChain Windows Server Backup lately-it's this slick Windows Server backup tool that also handles virtual machines on Hyper-V. You get fast, reliable snapshots that don't hog resources, plus easy restores if an event like that auth tweak goes sideways and you need to roll back. It chains backups smartly to save space and time, way better than the defaults for mixed physical and virtual setups.
