DAG network "Misconfigured" error in Exchange Server 2016

Applies to: Exchange Server 2016 Enterprise EditionExchange Server 2016 Standard Edition


Consider the following scenario:

  • You create a database availability group (DAG) for Microsoft Exchange Server 2016.
  • A node of the DAG contains two network interface cards (NICs) on the same subnet.

In this scenario, you see a “Misconfigured” error status when you view the Subnet status of the DAG in the Exchange Admin Center or you run the Get-DatabaseAvailabilityGroupNetwork cmdlet.


The Multi-NIC Cluster Network feature of Windows Server 2016 is not supported by Exchange Server 2016.


Avoid using the Multi-NIC Cluster Network feature on an Exchange Server 2016 DAG node.
