NS_E_BAD_ADAPTER_NAME
NS_E_BAD_ADAPTER_NAME — 0xC00D00CC
Treat this code as a record of invalid network adapter name: in the operation that returned it, the configured textual adapter name does not resolve to a current local interface object.
Place in the component lifecycle
Media delivery configuration combines a local adapter object, address, port, transport, route, multicast group, and TTL. In the context of invalid network adapter name, validate these dimensions separately so that a name-resolution error is not diagnosed as a firewall or bitrate problem. Locate the first component that changes state and distinguish later summary errors.
Important distinction. A valid adapter name can still have a bad address or route; this result occurs earlier at name resolution.
Build a reliable incident timeline
- Configured name, interface GUID/index, friendly name, and server version
- Current interface inventory and rename/reinstall history
- Cluster ownership or virtual-adapter lifecycle
- Known-good binding using stable interface identity
Tests that change one variable
- Enumerate interfaces through the same service context. Retain a known-good stream, session, or server object so a broad restart is not mistaken for repair of the reported failure.
- Replace display name with a stable supported identifier where possible.
- Recreate only the binding after an adapter rename. Keep media bytes, server identity, and unrelated publishing-point settings fixed.
How to interpret the comparison
- 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.
Repair and regression proof
Correction: Update stale configuration and avoid depending on mutable friendly names for automated bindings.
Accept the repair only when the name resolves to the intended interface across restart and traffic uses the expected address/route.
