HNS_VFP_PORTSETTING_NOT_FOUND

HNS_VFP_PORTSETTING_NOT_FOUND is an HRESULT used by Windows Host Networking Service (HNS). It indicates that the Virtual Filtering Platform setting expected on the target switch port is absent.

What to check

  • Confirm that the endpoint and its vSwitch port still exist before requesting the setting.
  • Compare the desired policy with the current VFP configuration rather than assuming it was retained.
  • Reapply the setting through the supported HNS or HCN workflow when the port is recreated.
