NS_E_INVALID_PUBLISHING_POINT_NAME
What the server is validating
This result (0xC00D1455) marks the proposed publishing-point name violates naming or path rules. Treat the symbolic name as a map to the owning Windows Media Services subsystem rather than as a request to reinstall every media component.
Publishing points are stateful server objects with a type, path, name, plug-in collections and start/stop lifecycle; broadcast, on-demand, cache/proxy and push points do not expose identical methods or valid transitions. In the trace, read the point type and status from the live server object model. When diagnosing this result, a name in an old MMC view or retained COM interface can describe an earlier generation.
Code-specific failure anatomy
A representative occurrence is when the proposed publishing-point name violates naming or path rules. Capture raw name, normalized name, separator characters, collision check and configuration source together with the object instance and the exact administrative or protocol request.
For a useful negative control, choose a valid stable point name and keep the content path in the separate Path property.
The tempting but misleading response is percent-encoding an invalid administrative name and assuming the server will decode it. That action does not test the distinction that matters here: duplicate push name is a collision with an otherwise valid name; invalid name fails before collision semantics.
What to record before changing anything
| Controlled comparison | Use a known-good object of the same type and vary only the precondition described as “the proposed publishing-point name violates naming or path rules”. |
Test the owning precondition
- Capture
0xC00D1455, the symbolic name, the exact API/administrative action and the first failure timestamp. - Preserve raw name, normalized name, separator characters, collision check and configuration source.
- Perform one isolated experiment: choose a valid stable point name and keep the content path in the separate Path property.
Comparison with adjacent states
Primary distinction: duplicate push name is a collision with an otherwise valid name; invalid name fails before collision semantics.
| Nearby result | Different condition |
|---|---|
NS_E_TOO_MANY_MULTICAST_SINKS | more than one multicast data writer is being enabled for one publishing point. |
NS_E_INVALID_PLUGIN_LOAD_TYPE_CONFIGURATION | a Windows Media Services plug-in registration exposes no supported activation mode. |
NS_E_PUBLISHING_POINT_INVALID_REQUEST_WHILE_STARTED | the requested administrative mutation is not legal while the publishing point is running. |
Changes that do not establish the cause
- percent-encoding an invalid administrative name and assuming the server will decode it.
- Avoid changing the publishing point, protocol, content and plug-in set in one test; such a test cannot show which precondition cleared the code.
