HNS_REQUEST_UNSUPPORTED

HNS_REQUEST_UNSUPPORTED is an HRESULT used by Windows Host Networking Service (HNS). It indicates that the operation, schema field, or combination of settings is unsupported on the current host.

What to check for HNS_REQUEST_UNSUPPORTED

  • Check the HNS or HCN API and Windows release support for the requested feature.
  • Verify the target network mode because an operation may be supported only by selected drivers.
  • Use a documented alternative rather than retrying the same unsupported request.
