You'll see Event ID 4614 and 4604 in the DFSR event log indicating sysvol replication has been initialized. No. If you had more than one affected DC, expand the steps to include ALL of them as well. Nonetheless, the bandwidth throttling is not 100% accurate and DFS Replication can saturate the link for short periods of time. Now watch this with DFSR Windows PowerShell : I just added RG, RF, and members with one pipelined command with minimal repeated parameters, instead of five individual commands with repeated parameters.

DFSRDIAG - DFS SyncNow - n StopNow - n PollAD - Active Directory DumpAdCfg - AD DumpMachineCfg - DFS The backlog count is the number of updates that a replication group member has not processed. It's possible for individual members of a replication group to stay within a quota before replication, but exceed it when files are replicated. Lets say Im the owner of an existing set of replication groups and replicated folders scattered across dozens or hundreds of DFSR nodes throughout the domain. For example, DFS Replication uses time stamps to determine which file takes precedence in the event of a conflict. Files are also staged on the receiving member as they are transferred if they are less than 64 KB in size, although you can configure this setting between 16 KB and 1 MB.
