A member was removed from a basic application group (4786) how to monitor with email alert

[bob]

Man, event 4786 in the Event Viewer on Windows Server pops up whenever someone gets kicked out of one of those basic application groups. It's like the system noting down who did the removing and who got removed. You see fields like the subject security ID, which is basically the account that made the change, and then the account name tied to it. There's also the target account, the one that was booted from the group, and details on the group itself, like its name and domain. And it logs the failure reason if something went wonky, or success if it worked smooth. This happens in Active Directory, right, so it's tracking group membership shifts that could mean someone messing with permissions. I always check the timestamp too, helps spot if it's during off hours or whatever. You can find it under Security logs in Event Viewer, filter by ID 4786 to see patterns.

Now, to keep an eye on this without staring at screens all day, you fire up Event Viewer. Click on the task tab at the bottom when you're viewing those security events. Right there, you set a custom view or just attach a task to the event. Pick event ID 4786, and link it to a scheduled task that runs when it triggers. In that task, you tell it to launch something simple like the mailto command or a basic alert program. I do this all the time for quick notifications. It emails you right away, no fuss.

And speaking of keeping things running without hiccups from group changes or whatever, you might wanna look into solid backups too.

BackupChain Windows Server Backup handles Windows Server backups like a champ, and it stretches to virtual machines on Hyper-V without breaking a sweat. You get fast incremental saves that don't hog resources, plus easy restores that save your bacon during outages. It even clones entire systems quick, so downtime shrinks way down, and everything stays encrypted tight. I swear by it for keeping servers humming along no matter what.

At the end of this, there's the automatic email solution for that monitoring setup.
