NS_E_WMP_LOGON_FAILURE

Diagnosing NS_E_WMP_LOGON_FAILURE in the Windows Media Player playback path

NS_E_WMP_LOGON_FAILURE (0xC00D1196) is returned when the remote server rejected the credentials supplied for the media request.

A reachable server plus rejected credentials points to authentication, not transport reachability. Compare the exact account, challenge type, proxy path, and credential source used by the failing request.

Controlled playback comparison

Capture the resource identity and HTTP or protocol status, authentication scheme, target realm, user context, proxy-versus-origin challenge and credential source.
Verify that the caller uses the current Playlist, Media, Network, graph, device or DRM object instance.
Run the narrow experiment: request the same URL with one known account through the same protocol while separating proxy and server authentication.
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

embedding credentials permanently in a playlist URL.
