Exchange 2010 Error While Adding Mailbox Server in DAG

An Active Manager operation failed. Error An error occurred while attempting a cluster operation. Error: Cluster API ‘”OpenCluster( failed with 0x6d9


After troubleshooting a lot we checked the Remote Registry Service was disable, I Changed it to Automatic and started the service then it was successfully added another DAG Member.

More over we need to check the network connection settings as well as IP address DNS Settings.
