Hello there,
LAPS automatically randomizes the local administrator password on all domain computers with LAPS activated and changes each password regularly.
If the expiration period has passed, the LAPS Group Policy Client Side Extension just checks the expiration date that is saved in AD, and the LAPS will update on the subsequent GP refresh.
In other words, if the password validity period is one year, it has been in use for that length of time.
Set the expiration time right away using the LAPS UI, and the LAPS will update once the next GP refresh occurs.
