Exchange Server 2010 DAG Troubleshooting.

DAG Group:

Error #1: You must provide a value for this property

Solution:

        Computer Object for DAG CNO must be set to disabled

DAG Membership:

Error #1: You must provide a value for this property

Solution:

Computer Object for DAG CNO must be set to disabled for the first DAG member added.

Warning #2: Network Name ‘<DAG_NAME>’ is not online.

Please check that the IP address configuration for the database availability group is correct.

    Solution:

         The replication may not yet start. You can check using powershell

cmdlet Get-DatabaseAvailabilityGroupNetwork

to check the replication status.

If the cmdlet shows error, it means that the replication is not yet started, either you can force the replication or wait for AD replication to occur.
