NS_E_TOO_MUCH_DATA_FROM_SERVER
What forced the disconnect
NS_E_TOO_MUCH_DATA_FROM_SERVER (0xC00D2F05) means the server sent too much data and the Windows Media client terminated the connection. Diagnose the size/framing of the specific response or stream segment rather than treating this as ordinary bandwidth saturation.
Evidence to capture
- Request method/URL, selected protocol and server/proxy identity.
- Declared response lengths or framing fields and the number of bytes actually received before termination.
- The point at which the client decided the data exceeded its accepted response boundary.
- Whether a proxy/gateway buffered, duplicated or transformed the server response.
Evidence to collect
| Field | What to preserve |
|---|---|
| Input | Exact URL/path, content hash or reference list presented to the parser/walker. |
| Selector | Parser, walker, protocol or stream type selected for that input. |
| Failure point | First rejected field, block, reference or stream offset when the component exposes it. |
| Lower result | First parser/read/protocol status before the server-level HRESULT is reported. |
Decision rule
A different file is only a control. The repair must make the original bytes or references pass the same parser/protocol boundary without silently substituting another input.
Focused test
Capture the same exchange with byte counts and framing intact, then compare it with a known compatible response for the same protocol. If a proxy is present, a supported direct-origin comparison can show whether excess data is introduced by the intermediary. Do not “fix” the symptom by merely increasing unrelated bandwidth limits.
Verification
Repeat the same request and confirm the response terminates at the expected protocol boundary without extra bytes or duplicated payload. If the connection now advances to a parser or media error, preserve that new HRESULT separately.
