Active Directory Lightweight Directory Services has detected a change of virtual machine generation ID. The change means that the virtual domain controller has been reverted to a previous state. Active Directory Lightweight Directory Services will perform the following operations to protect the reverted domain controller against possible data divergence  and to protect creation of security principals with duplicate SIDs:


Create a new invocation ID


Invalidate current RID pool


Ownership of the FSMO roles will be validated at next inbound replication. During this window if the domain controller held a FSMO role, that role will be unavailable.


Start SYSVOL replication service restore operation.


Start replication to bring the reverted domain controller  to the most current state.


Request a new RID pool.
