Event Type: Error
Event Source: NTDS Replication
Event Category: DS RPC Client
Event ID: 1645
User: NT AUTHORITY\ANONYMOUS LOGON
Active Directory did not perform an authenticated remote procedure call (RPC) to another domain controller because the desired service principal name (SPN) for the destination domain controller is not registered on the Key Distribution Center (KDC) domain controller that resolves the SPN.
Destination domain controller:
Verify that the names of the destination domain controller and domain are correct. Also, verify that the SPN is registered on the KDC domain controller. If the destination domain controller has been recently promoted, it will be necessary for the local domain controllers computer account data to replicate to the KDC before this computer can be authenticated.
