    a developer changed their password on Monday. Since then teh account locks every 15 minutes:

    This app can't run on your PC

    This app can't run on your PC

To find a version for your PC, check with the
software publisher.

    we suspect smth is still using teh old password, but they have a laptop, a phone, a tablet and who knows what else. how do we narrow it down?

    Weve already asked them to sign out everywhere, but thats easier said than done when nobody knows where everywhere is. Is there a reliable way to find the source of the bad password attempts? im about to throw this thing out the window lol

    yeahhh if teh caller is an Exchange or ADFS/web server, teh bad attempts come from outside (a phone or an attacker). check that servers logs (IIS logs, ADFS events) for the client IP and user agent. smart lockout on the cloud side and blocking legacy auth help a lot against password spraying.

    hmmm after a password change, the usual suspects are: phones with a mail profile still using the old password, mapped drives with saved credentials, Credential Manager entries, shceduled tasks or services running as that user, and disconnected RDP sessions on some server.

    lol same thing happened to me quick PowerShell to read lockouts from the PDC emulator:

    Get-WinEvent -ComputerName <PDC> -LogName Security -FilterXPath "*[System[EventID=4740]]" | Select-Object TimeCreated, Message

    The message includes the caller computer.
