RPC_NT_NOT_LISTENING
RPC_NT_NOT_LISTENING is an NTSTATUS value used by the Windows RPC runtime. This status reports that the RPC runtime is not in its listening state. Protocol sequences or interfaces may have been registered, but no active listener is accepting calls when the operation expects one. This is a local server-lifecycle condition.
It is the inverse of RPC_NT_ALREADY_LISTENING; neither describes a malformed endpoint. It also differs from RPC_NT_SERVER_UNAVAILABLE, which is observed from a client attempting to reach a remote server.
The requested RPC server operation requires an active listener
- Capture the return status of the listener-start API and any service shutdown, pause or stop event preceding the failure.
- Confirm that the process still owns the intended server runtime instance rather than a stale test instance.
- Verify protocol-sequence registration first, then listener state, then external reachability in that order.
