Diagnosing NS_E_WMP_NO_PROTOCOLS_SELECTED in the Windows Media Player playback path

NS_E_WMP_NO_PROTOCOLS_SELECTED (0xC00D11BE) is returned when all streaming transports usable by the Player have been disabled in configuration.

This is a configuration-state failure before a transport can be attempted. Record which protocols are disabled and verify the same resource after enabling only an appropriate supported transport.

Controlled playback comparison

Capture the resource identity and enabled protocol flags, policy values, Player Network settings and URL scheme.
Verify that the caller uses the current Playlist, Media, Network, graph, device or DRM object instance.
Run the narrow experiment: enable one supported protocol, restart the Player object and retry one known streaming URL.
Do not combine this focused test with a codec-pack change, Player reset, or broad registry cleanup.
If the retest returns a different specific HRESULT, diagnose that new failure as the next stage.

Actions that obscure the cause

opening firewall ports while the client has no transport selected.
