There are a couple of ways to check the progress of initial replication. You can either use the Event Viewer snap-in or WMI to check whether your replicated folders have finished initial replication.
Event Viewer:
A separate event (4104) is thrown for each replicated folder on each downstream partner. For example, if there are three downstream partners with four replicated folders each then a total of 12 events will be thrown on all downstream partners.
Open the Event Viewer snap-in on the server, navigate to the DFSR event log, and then check the 4104 events for your replicated folders.
WMI:
You can also check the status of initial replication by running the following command on the downstream machine. This is especially handy if the event log has been cleared.
C:\dfsr>Wmic /namespace:\\root\microsoftdfs path dfsrreplicatedfolderinfo get replicationgroupname,replicatedfoldername,state
ReplicatedFolderName ReplicationGroupName State
DATA Test-RG 4
The state for each folder that has completed initial replication is 4. For all other folders that are still in the process of initial replication, the ‘State’ will be 2.
