Ошибка "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"

Кластер не запускается из-за такой проблемы:
сетевой адаптер "Microsoft Failover Cluster Virtual Adapter" висит с желтым значком и имеет ошибку: "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"





Решение проблемы:
Check Device Manager and the Microsoft Failover Cluster Virtual Adapter has a yellow exclamation mark (this is netft.sys)

“This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)”

Need to remove the "Microsoft Failover Cluster Virtual Adapter" and reinstall it using the following steps:

1. From Device Manager/Network adapters, click on View-->Show hidden devices and then uninstall "Microsoft Failover Cluster Virtual Adapter"
2. Reboot the server for changes to take effect
3. After reboot Open Device Manager/Network adapters
4. From Action Menu Select “Add Legacy Hardware” and then click Next
5. Select “Install the Hardware that I manually selected from a list (Advanced)” and click Next
6. Select “Network Adapters” and then click Next
7. Select “Microsoft” From the left pane and select “Microsoft Failover Cluster Virtual Adapter” from the right list

8. Once the Adapter is added successfully you be able to start the cluster service successfully and let the DAG sync up the queue log files.

NOTE: If you reboot your server and issue comes back follow the same steps but disable IPv6 on the network adapters.
