What is 0xC000006A Account lockout?
The error appears when trying to log into an account with the correct username but an incorrect password. The 0xc000006A failure reason is listed as, unknown username or bad password. As stated, the accounts are not locked out in all cases, which puts administrators in a pickle.
Here are a few reasons users encounter the error:
- Incorrect login credentials: As in the error message, it’s most likely that the end user is entering incorrect login credentials, especially the password, triggering the error.
- Misconfigured settings: Often, misconfigured domain or network settings can lead to this situation. Check for recent changes and revert them.
- The password has expired: In many cases, the user’s password has expired, and they continue using the old one. So, verify that!
- Old password stored in the cache: Many administrators reported that the user’s password was stored in the browser’s or an application’s cache, which was subsequently used for login attempts. As a result, the 0xc000006a appeared in the event logs.
