NS_E_FILE_INIT_FAILED
Diagnosing NS_E_FILE_INIT_FAILED
0xC00D001F means Windows Media Services could not initialize the server-side file object needed by the operation. The failure is at open/create/setup time, before a normal read or write can be evaluated.
Evidence to collect
- canonical path and whether the operation expected to open, create, truncate or prepare the file;
- service account, desired access, sharing flags and creation disposition;
- the first filesystem/Win32 error from the initialization call;
- file type/expected container state if initialization includes validating an existing media file.
Focused test
Run the same initialization under the service identity against the same path. Separate path/ACL/share failures from format initialization by first proving that the file can be opened with the required disposition and then observing the first validation step.
Verification
The repair is complete when a fresh server file object initializes successfully and the next read/write or media-format stage begins. A later I/O HRESULT is a different failure.
