NS_E_NO_PDA
Where this result occurs in the Player workflow
NS_E_NO_PDA (0xC00D1179) marks enumerating a portable device for the requested Player operation. Preserve that boundary even when the visible Player message is broader than the producing operation.
Mechanism
At the checkpoint, windows Media Device Manager brokers between the Player, a device service provider and MTP, mass-storage or legacy device transports; Enumeration, Plug and Play identity, storage availability, format support and individual file operations are distinct checks. The page-specific boundary is enumerating a portable device for the requested Player operation.
A device shown in Explorer can still disappear from the Player’s WMDM session or reject a media format, filename, directory operation or storage request. A representative way to reach this result is that only a generic storage volume is present and no WMDM device is exposed.
State snapshot
| Evidence | Why it matters for no pda |
|---|---|
| Producing object and operation | PnP instance and interface path, WMDM service-provider CLSID, device/partnership ID, connection generation, storage object and capacity, format-support result, firmware version, operation callback and first device or transport HRESULT |
| Decisive observation | WMDM device count, PnP interfaces, service-provider activation and filtering criteria |
| Generation identity | Record the same disc, device, job or Player operation generation that returned this result; a reconnect or media change creates a different test. |
| Underlying result | Keep the first device, filesystem, COM, codec, DirectShow, IMAPI or BITS result seen before the Player mapped it to this result. |
| Controlled comparison | Repeat the producing call after changing only this condition: connect a supported device and refresh the Player device collection. |
How to interpret the next test
| Observation | Interpretation |
|---|---|
| The recorded values match the boundary | The result is consistent with enumerating a portable device for the requested Player operation; correct that state before changing unrelated codecs, drivers or playlists. |
| A lower layer failed before this result | Preserve that earlier HRESULT or device result because it may be only the Player-level mapping. |
| The same call passes after one isolated change | The comparison supports the no pda diagnosis rather than a broad installation failure. |
| The code changes after retesting it | The boundary was passed; diagnose the new HRESULT as the next independent stage. |
It scopes the failure to enumerating a portable device for the requested Player operation.
Controlled diagnostic sequence
- Capture
0xC00D1179, it, the exact Player/API operation and the first timestamp at which it appears. - Save WMDM device count, PnP interfaces, service-provider activation and filtering criteria; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- correlate the result with PnP instance and interface path, WMDM service-provider CLSID, device/partnership ID, connection generation, storage object and capacity, format-support result, firmware version, operation callback and first device or transport HRESULT.
- Reproduce once with the original source and destination, then apply only this change: connect a supported device and refresh the Player device collection.
- Create a fresh operation generation and verify that the original call advances beyond the no pda boundary.

Focused correction
For this occurrence, connect a supported device and refresh the Player device collection. Recreate only the object that produced it and repeat the original operation against the same controlled input.
When verifying it, do not assume the old interface pointer remains valid after reconnect; Re-enumerate the device and storage objects and correlate the failure with the same connection generation.
