3.2.4.2 Demotion
Demotion is the act of configuring a domain controller to no longer be a domain controller. At the beginning of demotion, ComputerOperationState MUST be set to DsRoleOperationActive. At the end of demotion, ComputerOperationState MUST be set to DsRoleOperationNeedReboot. Finally, all protocols on the server MUST be reinitialized to complete demotion.<10> The appropriate states of ComputerOperationState and ComputerRole are set during initialization according to section 3.2.3, regardless of the state of a demotion.
The operation or set of operations that constitute demotion (that configure a domain controller to no longer be a domain controller) are server-to-server operations and are not included in this document, and are not required for interoperation with clients.
