The error code "2016281112 Remediation failed" you're encountering typically means that the Intune service tried to remediate a settings violation, but it failed. This is often due to the device being offline, or the user not being signed in.
However, in your case, it seems to be related to Local Administrator Password Solution (LAPS) and the minimum password length policy.
Please double-check the following:
- Ensure that the local security policy on the devices does not conflict with the domain policy.
- Check the Event Viewer on the affected devices for any additional error messages or warnings related to LAPS or password policy. These will give you a better idea on where the issue could be emanating from.
- Make sure the devices are online and users are signed in when the policies are being applied.
- Verify that the LAPS extension is installed and functioning correctly on the devices showing the error.
