When requesting a password change the error: "NT_STATUS_ACCESS_DENIED " can be displayed:
This is a password change error inside the Windows operational system.
The error NT_STATUS_ACCESS_DENIED is related with the absence of the user’s permission to perform the password change, in this case, he can access the device and type the command, but the Windows return a permission absence error.
It’s important to verify if these changes were successfully performed before because a modification in the user’s policy can influence the error above.
