Look for the DFSC traffic in the filtered results or append the filter with DFSC in netmon or MA: tcp.port==445 and DFSC. The issue continues even on DCs in the same AD site as the PDCE, where AD replication occurs every 15 seconds and where you have run DFSRDIAG.EXE POLLAD on all the DCs. Distributed File System Replication (DFSR) is a replication engine that organizations can use to synchronize folders for servers on network connections that have a limited bandwidth. However, these tools are very limited. This command shows you the current replication state of DFS-R in regard to its DFS replication group partners. The cmdlet returns both inbound and outbound file replication information, such as files currently replicating and files immediately queued to replicate next. hence no action is required. - there are no errors when running repadmin /replsum, - there are no errors when running dcdiag on each DC, - in ADSIEDIT all domain controllers have the CN=DFSR-LocalSettings -> CN=Domain System Volume and CN=Domain System Volume exists under CN=System -> CN=DFSR-GlobalSettings.
