Repadmin /replicate command gives error DsReplicaSync() failed with status 8452 (0x2104)
I am getting issue while using Repadmin command between multiple domain controllers. I am having a setup of Windows 2003 servers on my network. Something is causing replication process to fail. I checked Event Viewer. But it is empty. There are no errors listed related to this. But I get error while using the command Repadmin /replicate. the error is related to some DsReplicaSync failure. Does anyone has idea about the same.

I am thinking that if UDP is not opened then other ports could be blocked without any knowledge by the network team. There are some important ports like the UDP emepheral ports that are also not supposed to be opened. For a Windows 2003 server the emepheral ports are UDP 1024-5000. Check the below article to see what ports are needed to be opened for AD client and DC to DC communications:
