It is a proprietary remote-procedure-call service; no protocol document, client, or server is publicly available, so the registration is essentially all there is to know. As with its neighbours, an open 1035 on a scan is far more likely to be a dynamically assigned Windows RPC endpoint from the old 1025-5000 range than the registered service.",
