Issue

Valid network interfaces should precede invalid interfaces in the binding order. A disabled or invalid adapter precedes a valid adapter in the network interface binding order list.

Impact

The binding order determines when network interfaces will be used to make network connections by the computer. A disabled adapter high in the binding order can degrade performance.

Resolution

Move all disabled and invalid interfaces to the bottom of the binding order list.

Configure the binding order so that the primary network interface used to communicate with DNS clients is first in the list. Configure interfaces that connect to secondary or backup networks lower in the binding order. Move all disabled or invalid interfaces to the bottom of the binding order, or remove them from the list.

To move all disabled and invalid interfaces to the bottom of the binding order list

  1. Click Start, click Network, click Network and Sharing Center, and then click Manage Network Connections.

  2. Press the ALT key, click Advanced, and then click Advanced Settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

  3. Click the Adapters and Bindings tab, and then, under Connections, click the connection you want to modify.

  4. Under Bindings for <connection name>, select the protocol that you want to move up or down in the list, click the up or down arrow button, and then click OK.
