NS_E_INVALID_BLACKHOLE_ADDRESS
NS_E_INVALID_BLACKHOLE_ADDRESS — 0xC00D0040
This result belongs to uninitialized blackhole address not to a generic restart checklist, because the special discard destination used by the legacy media server has not been initialized with a valid address.
Operational meaning
Media delivery configuration combines a local adapter object, address, port, transport, route, multicast group, and TTL. In the context of uninitialized blackhole address, validate these dimensions separately so that a name-resolution error is not diagnosed as a firewall or bitrate problem. Locate the first component changing state in this condition and distinguish later summary errors.
Important boundary. This is not a general DNS or remote-host failure; it concerns a server-internal configured discard destination. Record the exact constant and returning API.
Facts worth preserving
| Capture | Diagnostic question |
|---|---|
| Configured blackhole address, adapter/interface context, address family, and server startup sequence | Separates configuration or identity from storage, parser, network, or lifecycle state. |
| Feature or diagnostic path that requests the blackhole destination | Provides a stable before/after comparison for the proposed correction. |
| Network configuration changes and initialization events | Shows whether the status is expected information, a warning, or the first failure in the event sequence. |
| Whether the address is expected to be local, nonroutable, or a server-owned sentinel | Ties the message to one server object and one transition instead of a later retry. |
Prefer identifiers, versions, counts, hashes, state transitions, and redacted paths; media content, credentials, keys, and user data are rarely needed in routine incident logs.
Reproduce the boundary safely
- Initialize the address through the supported configuration path and restart only the dependent component. Retain a known-good stream, session, or server object so a broad restart is not mistaken for repair of the reported failure.
- Compare with a clean server configuration of the same version. Record the first server event, object state, or return value that changes.
- Trace address selection to confirm that production traffic is not accidentally routed there. Keep media bytes, server identity, and unrelated publishing-point settings fixed.
Stop after the first comparison that moves the boundary and diagnose the replacement status independently instead of accumulating unrelated server changes.
What not to infer
- Known-good comparison succeeds: isolate the production object or configuration associated with the failing operation.
- Same failure on the control: investigate the shared server, plug-in, storage, topology, or network layer before changing media content.
- Different status after one change: preserve both results; the first rejected condition was removed, but the operation is not yet proved complete.
Closing the incident
Correction: Restore the supported blackhole-address configuration and ensure initialization precedes any feature that uses it. Keep the original server configuration, event sequence, object inventory, input hash, and topology snapshot so the change can be reversed and explained.
Accept the repair only when the feature resolves the intended discard destination and normal media traffic continues to use its configured interfaces. Repeat the original supported operation under the original identity and object state; a simplified media file, replacement server, new session, or different client is useful comparison evidence but not final regression proof.
