What does HRESULT 0xC00D11CB (NS_E_WMP_NETWORK_RESOURCE_FAILURE) mean?

NS_E_WMP_NETWORK_RESOURCE_FAILURE

Diagnosing NS_E_WMP_NETWORK_RESOURCE_FAILURE in the Windows Media Player playback path

NS_E_WMP_NETWORK_RESOURCE_FAILURE (0xC00D11CB) is returned when a network resource used by the Player failed after initial configuration, without a more specific retained mapping.

Record what the Player had already completed because later retries often replace the original evidence. The specific rejected condition is a network resource used by the Player failed after initial configuration, without a more specific retained mapping.

Controlled playback comparison

1. Start from the original call and log 0xC00D11CB together with its object and operation phase.
2. Collect resource URL, share or socket handle, earliest OS error, reconnect attempts, network-change events and server logs before changing the machine.
3. Use this single-variable test: repeat in a fresh Player process while tracing handle creation and the first failing I/O call.
4. Repeat on a fresh object if the original predates a configuration, device or resource change.
5. Validate the expected next operation, not just initial open or object creation.

Actions that obscure the cause

• restarting repeatedly without preserving the first OS error.
