DFS Member not replicating

Hello.

I have 3 DFS Members each at different sites (Server1,Server2,Server3)

all were replicating previously but Server 3 is no longer replicating/reflecting the changes made from it.

i.e Server 3 creates/deletes/changes a file this change is not reflected on Server1/2

Server1/2 creates or deletes a file this is reflected on Server3

Reviewed the event logs, ran a DFS Diagnostics report.. dont see any backlogged files or errors.

Ran DCDIAG at all sites no replication issues

Able to ping each file server .

Any ideas?
