What does HRESULT 0xC00D1197 (NS_E_WMP_CANNOT_FIND_FILE) mean?

NS_E_WMP_CANNOT_FIND_FILE

Diagnosing NS_E_WMP_CANNOT_FIND_FILE in the Windows Media Player playback path

NS_E_WMP_CANNOT_FIND_FILE (0xC00D1197) is returned when the library item or requested URL resolves to a local or remote object that no longer exists at that location.

Record what the Player had already completed because later retries often replace the original evidence. The specific rejected condition is the library item or requested URL resolves to a local or remote object that no longer exists at that location.

Controlled playback comparison

1. Start from the original call and log 0xC00D1197 together with its object and operation phase.
2. Collect stored sourceURL, normalized path, file ID, share mapping, case, link target and library record timestamp before changing the machine.
3. Use this single-variable test: open the exact resolved path outside the Player under the same account, then update the library item only if location changed.
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.
