Hi Matthieu:
We may need to do time travel tracing but I want to look at network traces first. I looked at the original email and I don't see any traces attached to it.
Can you please send the network traces?

That's because I got fooled by the logs, as between the DsReplicaRequest and the DsReplicaResponse there was a GetNcChange response.
But look at the capture, every time samba sends a DsReplica we get a DS_DRA_NO_REPLICA answer.
What are the causes of this behavior ? Do you want me to timetrace (not too convenient).
