Situation: After configuring LAPS, the client finds some computers’ local administrator password generated by LAPS doesn’t work. They have multiple IT people to try it. LAPS UI and Get-AdmPwdPassword -ComputerName pco1 shows the same password. But the PC doesn’t take it. They also run gpupdate /force on the PC.
Troubleshooting: we find the problem. Some apps and services use administrator account with original password to login. That locked the administrator account.
