40 /* The "real" RPC portmapper endpoints that I know of are:
44 * ncacn_np: \\pipe\epmapper
48 * If the user's machine ran a DCE RPC daemon, it would
49 * probably be possible to connect to it, but there are many
50 * reasons not to, like:
51 * - the user probably does *not* run one, and probably
52 * shouldn't be forced to run one just for local COM
53 * - very few Unix systems use DCE RPC... if they run a RPC
54 * daemon at all, it's usually Sun RPC
55 * - DCE RPC registrations are persistent and saved on disk,
56 * while MS-RPC registrations are documented as non-persistent
57 * and stored only in RAM, and auto-destroyed when the process
58 * dies (something DCE RPC can't do)
60 * Of course, if the user *did* want to run a DCE RPC daemon anyway,
61 * there would be interoperability advantages, like the possibility
62 * of running a fully functional DCOM server using Wine...
