Nothing to lose at this point. This could be due to lack of availability of disk space or due to sharing violations. To resolve theissue, we need to manually resume replication. Available in Windows Server 2008 R2 and later, it acts as a replacement for the DFS Namespaces replication engine, Microsoft says. Unfortunately, the prospects of Microsoft fixing these deficiencies is not likely. Five Common Causes of Waiting for the DFS Replication service to retrieve replication settings from Active Directo Five Common Causes of Waiting for the DFS Replication service to retrieve replication settings from Active Directory, Fixing Replication DNS Lookup Problems (Event IDs 1925, 2087, 2088), Fixing Replication Connectivity Problems (Event ID 1925), Troubleshooting RPC Endpoint Mapper errors using the Windows Server 2003 Support Tools, Outdated Active Directory objects generate event ID 1988 in Windows Server 2003. This command shows you the current replication state of DFS-R in regard to its DFS replication group partners. The service will automatically try to clean up the staging folder again. My process has been: 1. We have seven remote 2008 R2 file servers that is synchronizing to one Server 2012 R2 server la Hub and Spoke.

DFSR Event ID 2213 is triggered after a dirty shutdown which provides commands to resume the specified replicated group manually. Distributed File System Replication - DFSR operates in a multi-master, state-based design. Modify the registry at your own risk. Log on to the DFSR server where data is not replicating and if space is available, locate the affected replicated group and open group properties to increase the staging area on the staging tab to maximum affordable value. DFSR Event ID 2213 is triggered after a dirty shutdown which provides commands to resume the specified replicated group manually. This is the default behaviour with the 2012 server.

I also increased the size of the Staging on the 2008 server for good measure, even though that's not the server reporting the error. DFS-R is effectively a black box, indicating nothing about the current status of the service. Note that for the initial sync process the maximum staging area is required, once the process has finished successfully its utilization is limited to data being changed at both sides, so we can set it to a lower value to save disk space.

Description: I have a weird problem, our DFSR have stopped working on one of our servers. 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. 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. With the release of Windows 2012 R2 / Windows server 2016, the above registry is already created by default when you install DFSR and its value is set as 0, In fact, if you deleted the registry entry, there wouldn't be an issue.
