Abstract
The present invention extends to methods, systems, and computer program products for domain controller safety-features and cloning. Embodiments include cloning virtual domain controllers. Cloning permits virtual domain controllers to be rapidly deployed by copying/cloning the entire operating system state of an existing virtual domain controller. Other embodiments provide safety features protecting domain controllers running within virtual machines from introducing distributed corruption into a directory services data system. Protection is facilitated by detecting when a hypervisor or Virtual Machine Manager (“VMM”) uses features that cause a virtual machine to be rolled back in time outside of an operating system's awareness. In response to detecting a feature that causes rollback, safeties can be implemented to compensate for otherwise divergent state and prevent the introduction of duplicate unique identifiers.
