ERROR_CLUSTER_NETWORK_NOT_FOUND
The referenced network does not exist in the cluster view. The physical adapter can still exist, so verify network discovery and interface state instead of assuming that the NIC must be reinstalled.
Check whether Cluster service network discovery still sees the underlying subnet on any node. A renamed or replaced adapter may require topology convergence, while a missing physical path requires network repair outside the cluster database.
What to check
- Compare the expected subnet and adapter with the networks and interfaces discovered by the cluster.
- Check whether the adapter is disabled, disconnected, excluded, or has an address that no longer matches the expected network.
- Use a fresh cluster log and validation report when the network disappeared during a membership change.
