Fixing Duplicate Network Adapter Names

Duplicate Network Adapter names may appear in Device Manager after the initial software installation or when adding Ethernet PCIe adapter cards. The duplicate names will cause incorrect reporting of network information, in which case, teamed adapters will not be duplexed.

To fix duplicate network adapter names

1. Delete any teams that contain adapters with duplicate names.

2. In Device Manager, right-click an adapter with a duplicate name, and select Uninstall on the drop-down menu to uninstall the adapter. Repeat for other adapters with duplicated names.

3. Use the Scan for hardware changes command to reconfigure the network adapters with unique names. To use Scan for hardware changes:

   1. Select Device Manager.

   2. In Device Manager, expand Network adapters.

   3. Right-click the target adapter and select Scan for hardware changes.

4. Create any required teams again.

Use Windows Remote Desktop if you need to start Device Manager remotely. You can then create or modify a team if it is not carrying your connection to the system.
