Resolve Network Binding Order Warning in failover cluster

In this post, I’m going to talk about an issue that I found while running the cluster validation report. You may receive below warning message that includes information about the cause of the warning, which can help you to resolve the issue.
Rule “Network binding order” generated a warning.
The domain network is not the first bound network.  This will cause domain operations to run slowly and can cause timeouts that result in failures.  Use the Windows network advanced configuration to change the binding order.

In the below screenshot, the warning says the network card used to connect to your domain network is not at the top of the network binding order.

Step 2:

In this case the Microsoft Failover Cluster Virtual Adapter is bound before the domain network and still the cluster validation report shows you warning. In the below screenshot, the TeamNIC_MGMT NIC adapater is my domain network and was already at the top of the binding order.
