No template file, test, or entry point is identified in the issue. Start by locating the 301-storage-spaces-direct DSC template and reviewing its domain-join deployment parameters, then reproduce the deployment and trace the adminUsername conflict. Done means both VMs join the domain without the PropertyChangeNotAllowed error.
