FWP_E_IKEEXT_NOT_RUNNING
FWP_E_IKEEXT_NOT_RUNNING means the operation requires the IKE and AuthIP IPsec Keying Modules service (IKEEXT), but the service is not running. Windows starts this service when IPsec policy requires it.
What to verify
- Check the current service state and any service-start failures in the Windows event logs.
- Confirm that required IPsec policy is present; IKEEXT may be trigger-started rather than continuously running.
- Do not disable IKEEXT as a troubleshooting shortcut when the system uses IPsec, because that prevents IKE/AuthIP key exchange.
