Unable to obtain the administrator password to use an AWS EC2 instance that has a Windows OS

This error occurs after the instance is launched from an AMI that is converted using automated disaster recovery.

The following error is displayed:

Password is not available. This instance was launched from a custom AMI, or the default password has changed. A password cannot be retrieved for this instance. If you have forgotten your password, you can reset it using the Amazon EC2 configuration service. For more information, see Passwords for a Windows Server Instance.
