Each computer may show an alert icon on the right side of its entry. This indicates that the state of that computer’s LAPS managed password:
Password Expired Warning
This symbol indicates that the LAPS password has expired and is due to be refreshed by the system. If this remains in this state for a long time, it may indicate that the computer is not processing its LAPS policy correctly.
Password Not Set Warning
This alert indicates that the computer does not have any LAPS password data in Active Directory. If your LAPS installation is new, or the computer has only recently been added then this may be normal.
