Whenever we create a DFS namespace and DFS Replication group, the namespace and replicated group are stored into the active directory domain partition and if AD replication is failing, then the changes are not replicated to the remote domain controller, hence the DFS server in that site could not get those changes and could not initialize initial sync (one way sync). Lingering objects may remain after you bring an out-of-date global catalog server back online o I setup DFSR a few hours ago, but it does not seem to be configured on all the servers.
