This object monitors configuration updates with Active Directory Domain Services (AD DS), and creates a Warning alert if it detects that DFS Replication couldn’t update AD DS. It does so by looking for the presence of DFS Replication Event 6016.
An unhealthy state of this monitor indicates that DFS Replication failed to update its configuration in Active Directory Domain Services (AD DS). This can occur if the only domain controllers that the server can reach are read-only domain controllers.
Wait for configuration changes to replicate with AD DS
DFS Replication will retry this operation, which usually resolves automatically after configuration changes replicate through AD DS.
To poll immediately for configuration changes, open a command prompt window and then type the following command once for each member of the replication group, where <domain> is the domain the server is located in and <server> is the server name:
Dfsrdiag PollAD /Member:<domain>\<server>
If this problem persists, verify that AD DS replication is working and that the service is able to reach a domain controller. If the problem persists for 8 hours, the DFS Replication service will disable the connection and log DFS Replication Event 5016.
This monitor automatically resets to a healthy state when the issue is resolved.
