During an Active Directory Domain Services replication request, the local domain controller (DC) identified
a remote DC which has received replication data from the local DC using already-acknowledged USN
tracking numbers.



Because the remote DC believes it is has a more up-to-date Active Directory Domain Services database than the
local DC, the remote DC will not apply future changes to its copy of the Active Directory Domain Services
database or replicate them to its direct and transitive replication partners that originate from this
local DC.



If not resolved immediately, this scenario will result in inconsistencies in the Active Directory Domain Services databases
of this source DC and one or more direct and transitive replication partners. Specifically the
consistency of users, computers and trust relationships, their passwords, security groups,
security group memberships and other Active Directory Domain Services configuration data may vary, affecting the ability to log on,
find objects of interest and perform other critical operations.



To determine if this misconfiguration exists, query this event ID using http://support.microsoft.com
or contact your Microsoft product support.



The most probable cause of this situation is the improper restore of Active Directory Domain Services on the
local domain controller.



User Actions:

If this situation occurred because of an improper or unintended restore, forcibly demote the DC.
