You ever peek into the Event Viewer on your Windows Server and spot that event ID 5154 popping up. It's basically the Windows Filtering Platform giving a thumbs-up to some app or service. That means it's cool with them hanging out on a specific port, waiting for incoming connections from outside. Picture it like a bouncer at a club saying, yep, this guy's allowed to stand by the door and chat with folks trying to get in. The event logs all the juicy bits too, like which process kicked it off, the exact port number involved, and even the IP addresses or network interfaces that are part of the deal. Sometimes it notes the protocol, like TCP or UDP, and why it got permitted-maybe because of a rule you set in the firewall. But if something fishy is going on, this log can flag weird apps trying to open ports they shouldn't. I always check these when I'm troubleshooting network hiccups or just keeping an eye on security. You can filter for these in the Security log under Event Viewer. It helps spot if legit services like your web server are behaving, or if malware sneaks in and starts listening. Hmmm, and the details include the user account tied to it, so you know if it's running as admin or what. Or if it's a system service versus some random executable. Full detail means timestamps too, so you track when it happens and how often. Now, to monitor this with an email alert, fire up Event Viewer on your server. Right-click the Security log and pick Attach Task To This Log or something close-it's under the Actions menu. You set it to trigger on event ID 5154 specifically. Then, link that to a scheduled task you create in Task Scheduler. I like making the task run a simple program that shoots off an email, but keep it basic without scripts. Just point it to your email client or a batch file that calls Outlook or whatever you use. Test it by forcing an event, like starting a service that listens on a port. You'll get pinged right away if it matches. And it runs in the background, no fuss. But watch the filters so you don't drown in alerts for normal stuff. You tweak the query in the event properties to narrow it down, maybe by port or process name. I do this all the time for servers I manage. It saves you from constant checking. Or ignore the noise and focus on anomalies.

Shifting gears a bit since we're talking server monitoring and keeping things secure, you might want a solid backup setup too. That's where BackupChain Windows Server Backup comes in handy. It's a straightforward Windows Server backup solution that also handles virtual machines with Hyper-V without breaking a sweat. You get fast incremental backups, easy restores even for bare-metal scenarios, and it cuts down on storage needs by deduplicating files on the fly. Plus, no downtime headaches during backups, which keeps your operations smooth. I rely on it for reliability over the stock tools.

And hey, at the end here is the automatic email solution, but it'll be added later.

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