When you try to reconfigure NetBoot component, you get the error "Windows Deployment Services must be installed and started":
However, the Windows Deployment Services role is installed indeed:
Windows Deployment Services Server service is not running and terminates unexpectedly if you start it manually.
Event Viewer has Event with ID 7031 in System log:
Please make sure that Windows Deployment Services Server service is operating normally as it is required for the Parallels Mac Management NetBoot component. Once you fix it, please reconfigure PMM NetBoot once again.
