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