I've been dealing with a strange issue at work where my Active Directory account keeps getting locked out three days in a row. Since it's a small company with only 15 users and I have admin rights, I'm a bit worried. It appears that someone might be trying to log in and failing three times, but nobody is entering my office, except for the cleaning lady after hours. I've checked around but I'm not very tech savvy. What could be causing this, and how can I fix it while ensuring our data remains secure?

Make sure you’re not logging in with your admin account for daily tasks—it's bad practice. Use a standard account for regular work, and have a separate admin account that you only use when necessary. This can help reduce vulnerabilities and avoid lockouts if something's trying to use your old credentials elsewhere.
Exactly! If you’re managing your own devices, it helps to have a clear separation between user accounts and admin privileges.
It sounds like you might be dealing with stale credentials somewhere. Check your Credential Manager for any outdated domain credentials that could be causing this. Also, consider if there's a mapped network drive or any apps that might be storing old passwords; they can lead to repeated lockouts. A brute force attack is possible, but it seems unlikely given what you described. Just stay calm and explore the issue systematically!
Also think about wireless devices—like your phone—storing your old credentials. That can often trigger lockouts if it's trying to connect with an outdated password.
If you've got other workstations, check if any of them are still logged in with your old credentials. That’s something we've had issues with before.
Just a heads-up—if the cleaning lady is coming in after hours, there's a small chance that she could be inadvertently locking you out if she’s using your keyboard. Keep an eye on that, or maybe lock your computer when you leave for the day!
That's an interesting thought! I'll definitely start locking my screen whenever I step away.
Yeah, any physical access could lead to unintended logins, so stay vigilant!
You should definitely check if your account is logged in on any other devices. I had an issue once where my old phone was trying to use stored credentials, causing frequent lockouts. If you've used your account anywhere else and changed passwords afterward, that could be the culprit too.
That happened to me when I forgot about an RDP session left open. Make sure all sessions are signed out.
And don’t forget about any old passwords saved on mobile devices; they can cause these lockouts!
You might want to check the event logs on your domain controller for Event ID 4740, which tells you which computer is causing the lockout. This could give you insights into where the failed login attempts are originating. Don't forget to check for Event ID 4625 for additional info on failed logins.
You can also use tools from Microsoft that can help track account lockouts more easily, like the Account Lockout Status tool.
Yep, filtering through those logs can be super helpful. If you have logging enabled, you'll also see time and date stamps for each lockout.
Totally agree! It's vital to keep admin tasks separate. Having your daily driver account as an admin is a risky move.
