Scenario: When troubleshooting cluster related issues, we found we could not start the cluster service. When we tried to start the service, we found the following entry in the System log:
Event ID: 7000 – Source: Service Control Manager
The Cluster Virtual Miniport Driver service failed to start due to the following error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.
Solution: In our case, the Microsoft Failover Cluster Virtual Adapter was no longer present under Network Adapters (View –> Show Hidden Devices) in the Device Manager. To reinstall it, perform the following:
- Click on the server at the top of the device manager
- Add legacy hardware
- Install Hardware Manually
- Select Network Adapters
- Select Microsoft
- Select Microsoft failover cluster virtual adapter
