The DC promotion process results in the configuration, starting, and stopping of several services. If those services are started during the course of the DC promotion process, this problem can arise.
Ensure that no system services are started during the course of DC promotion. Services can be started by group policy settings enforced during an unexpected GPUPDATE, or by other applications.
