Once Initial replication completed, DFSR logs event ID 4104 which states that all data is synced and data can be replicated back and forth now. Level: Error Therefore, the SYSVOL and NETLOGON folders for the domain controllers are no longer shared, and the domain controllers stop responding to location questions from clients in the domain. DFS is active directory aware application and heavily depends upon AD sites and services and AD replication. The majority of DFSR issues arise because of active directory replication issues, inadequate staging quota, sharing violations of open files, a corrupted DFSR database, unexpected dirty database shutdowns, conflicting data modifications, and accidental data deletion.

This can occur if the service terminated abnormally (due to a power loss, for example) or an error occurred on the volume. 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. This topic has been locked by an administrator and is no longer open for commenting. However, these tools are very limited.

This command shows retrieves pending updates between two computers that participate in DFS-R file replication service. On the affected DC, run: Validate that the DC now shares SYSVOL and NETLOGON, and replicates SYSVOL inbound. One of the best ways to check the health of the SYSVOL replication using DFSR is to install the Distributed File System management tools on a machine. Thanks for contributing an answer to Server Fault! I'm wondering if all servers require this at once for it to proceed.
