This object monitors replicated folders that were recently brought online and creates a Warning alert if any of the replicated folders were offline for too many days. It does so by checking for the presence of DFS Replication Event 4012 in the DFS Replication event log.
This monitor enters an unhealthy state if a member of a replication group has been offline (disconnected from other members of the replication group) for longer than the MaxOfflineTimeInDays parameter, and then is brought back online. This can occur if the server is running Windows Server 2008 R2 or Windows Server 2008, “content freshness” (the MaxOfflineTimeInDays parameter) has been enabled, and any of the following conditions exist:
An administrator disabled or deleted the replication connection.
An administrator changed the replication schedule in a way that prevents replication.
The DFS Replication service has been stopped for an extended period.
The server has been offline.
Disable and enable the computer’s membership in the replication group
To resolve this issue, back up all data in the affected replicated folders, and then see Implementing Content Freshness Protection In DFSR (http://go.microsoft.com/fwlink/?LinkId=187089) for information about how to recover from this situation by disabling and then enabling the computer’s membership.
Caution: After enabling a replicated folder, DFS Replication performs the initial replication by using the primary member’s files as authoritative regardless of the age, potentially overwriting newer files.
Note: Membership in Enterprise Admins, or equivalent, is required to complete this procedure. See Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477) for details about using the appropriate accounts and group memberships.
After replication completes, this monitor automatically resets to a healthy state.
To manually confirm that replication is healthy, run a propagation test on the affected folder by using DFS Management or the following commands, where <ReplicationGroup>is the name of the replication group and <ReplicatedFolder>is the name of the replicated folder:
dfsrdiag propagationtest /rgname:"<ReplicationGroup>" /rfname:"<ReplicatedFolder>" /testfilename:DFS-RTestFile.xml
dfsrdiag propagationreport /rgname:"<ReplicationGroup>" /rfname:"<ReplicatedFolder>" /testfilename:DFS-RTestFile.xml /reportfilename:c:\DFS-R_Report.xml
