What does HRESULT 0xC00D1585 (NS_E_INVALID_LOG_URL) mean?

NS_E_INVALID_LOG_URL

Where the condition occurs

This result (0xC00D1585) marks the multicast logging URL does not match the HTTP endpoint form expected by the logging path. The code identifies a narrow server contract, so diagnosis should preserve the object instance and the first native return.

Code-specific failure anatomy

A representative occurrence is when the multicast logging URL does not match the HTTP endpoint form expected by the logging path. Capture exact LoggingURL, scheme, host, path, escaping and reachability from receiving clients/server as applicable together with the object instance and the exact administrative or protocol request.

For a useful negative control, configure a valid HTTP logging endpoint such as the intended ISAPI/backend path and send one test log.

The tempting but misleading response is using the multicast media URL as the logging URL. That action does not test the distinction that matters here: authorization file not found concerns local authorization data, not the syntax of a remote logging endpoint.

Build a reproducible incident record

A controlled correction

1. Capture 0xC00D1585, the symbolic name, the exact API/administrative action and the first failure timestamp.
2. Preserve exact LoggingURL, scheme, host, path, escaping and reachability from receiving clients/server as applicable.
3. Perform one isolated experiment: configure a valid HTTP logging endpoint such as the intended ISAPI/backend path and send one test log.
