Some servers have Event 5004 'The DFS Replication service successfully established an inbound connection with partner for replication group Domain System Volume.' To resolve this issue we need to rebuild theDFSR database on theaffected member. The purged file now needs to be replicated from the source server again. The ideal solution to this case is to keep the staging area to be as equal to the data size being replicated, since this is not possible, we should increase the staging area to be as maximum as possible / affordable by comparing the size of data to be replicated and available disk space on the primary / secondary or both servers based on event log occurrence.
