MQ_ERROR_NO_RESPONSE_FROM_OBJECT_SERVER: the remote owner of the MSMQ object did not answer the request

MQ_ERROR_NO_RESPONSE_FROM_OBJECT_SERVER (0xC00E0049) identifies a specific boundary: the remote owner of the MSMQ object did not answer the request. Keep it separate from neighboring errors that may occur in the same product but represent a different lookup, state, trust, or transport decision.

Evidence to capture

Preserve the object identity, owner/server address, RPC or MSMQ request ID, timeout, and the last successful exchange. This differs from “owner unavailable”: here a request was sent but no response arrived in the expected interval.

Corrective test

Repeat against the same owner after confirming service responsiveness and transport reachability. A connection refusal or name-resolution failure is a different boundary and should be logged separately. Preserve the original identifiers while testing; if another HRESULT appears after this boundary is fixed, treat that value as the next-stage result.
