HNS_DEGRADED_OPERATION
HNS_DEGRADED_OPERATION is an HRESULT used by Windows Host Networking Service (HNS). It indicates that the target network, endpoint, or related resource is in a degraded state.
What to check for HNS_DEGRADED_OPERATION
- Inspect HNS, Host Compute Service, Hyper-V, and network event logs for the original failure.
- Determine which dependent adapter, switch, policy, or endpoint is unhealthy before retrying.
- Repair or recreate only the affected object after confirming the impact on active workloads.

Diagnostic discriminator: Identify the specific HNS dependency that is degraded—adapter, switch, endpoint or policy—before recreating objects. This result describes partial health, so broad network reset is not justified without dependency evidence.
