NS_E_INSUFFICIENT_BANDWIDTH
NS_E_INSUFFICIENT_BANDWIDTH — 0xC00D002C
What failed
NS_E_INSUFFICIENT_BANDWIDTH means the bandwidth available to Windows Media Services is not enough to fulfill the request. Unlike NS_E_MAX_BITRATE, this result is about available capacity for the request, not merely a configured maximum-bitrate ceiling.
Capture before retry
- The requested stream/operation bitrate and selected content variant.
- Available or reserved bandwidth reported by the server/publishing point at the failure time.
- Concurrent sessions and any reservations that consume the same resource.
- The policy or plug-in that calculates/admits bandwidth, if the deployment uses one.
Evidence to collect
| Field | What to preserve |
|---|---|
| Ceiling | Exact configured limit, its unit and the server/publishing-point object that owns it. |
| Current use | Measured count/rate/size immediately before the rejected request. |
| New demand | Amount the new operation would add to the same resource. |
| Owners | Sessions, titles, streams or reservations contributing to the measured usage. |
Decision rule
The result is proved only when recorded usage plus the new demand crosses the recorded ceiling; otherwise investigate stale accounting or the object that owns the limit.
Focused test
Repeat the same request after changing one capacity variable: free a known reservation/session, select a lower-bitrate representation, or increase the documented available capacity. Keep the endpoint and protocol unchanged. This separates a real admission/capacity problem from connectivity or protocol negotiation.
Verification
Confirm the same request is admitted with measured available bandwidth at or above its requirement. Then reproduce a controlled insufficient-capacity case to ensure the server still rejects work instead of oversubscribing silently.
