Hello,
Thank you for your question.
- I would suggest you to reboot server after LAPS installed.
- Please check AD replication is in good health and are in Sync with all other DCs.
3 Please move the computer or user account to right OU or group where the LAPS GPO applied. - On the client computer run gpresult /h C:\temp\gpresult.html to check if the GPO is applied and which GPO is winner,
Hope this helps.
