ERROR_CLUSTER_NO_NET_ADAPTERS
ERROR_CLUSTER_NO_NET_ADAPTERS means the cluster service cannot find usable network adapters on the node. This can result from disabled adapters, drivers, virtual-switch changes, or adapter configuration that no longer matches cluster requirements.
What to check
- Verify that the physical or virtual adapters are enabled and have the expected IP configuration.
- Compare adapter and VLAN configuration with a healthy node.
- Run network validation after correcting the underlying interface issue.
