FWP_E_NET_EVENTS_DISABLED
FWP_E_NET_EVENTS_DISABLED means that WFP diagnostic network-event collection is disabled. It does not prove that a filter did not match or that the network stack is broken; it means the requested diagnostic event stream is unavailable under the current engine configuration.
Distinguish collection from subscription
Subscribing for net events requests delivery to a callback, but there must also be event collection to deliver. Microsoft documents engine options for collecting network events and notes that some event-collection settings persist across reboots.
Careful remediation
- Verify whether diagnostics are intentionally disabled by policy, privacy controls, or a security product before enabling them.
- Enable only the categories needed for the investigation, capture the evidence, and return to the approved operational setting.
- Keep the callback fast and avoid treating diagnostic events as a complete audit trail unless loss and retention behavior are handled explicitly.
