DFS-R replication issue - 1 server not in sync

Question

Hi,

I have DFS-R replication issue with windows 2019 environment. I have 4 servers, out of that 2 are online or running. When ever i save data on the replicated folder in server 1 it replicates immediately to server 2. But same way if i do it in server 2, it wont get replicated to server 1. This is a frequent issue now, I may need to re add the replication group and folders every time to solve this issue.

As per the diagnostic report, it says - Due to ongoing sharing violations, DFS Replication cannot replicate files in the replicated folders listed above. This problem is affecting 10 files in 1 replicated folders. Event ID: 4302

Could some one help here please to solve this ?

Thanks
Arun

Hi,
Welcome to share here!

To determine the real state of the file, use the DFSRDIAG BACKLOG command to check for sharing violations. The command output provides a list of the first 100 files that are not replicated.
dfsrdiag backlog /rgname:slowrepro /rfname:slowrf /sendingmember:server1 /receivingmember:server2
