I'm familiar with Sun's RPC, not DCE's, but a quick scan suggests a
similar implementation, which means the port chosen for a service is not
deterministic. I didn't find something analogous to the Sun portmapper
but I probably didn't just look hard enough. One could block that. (I'm
thinking of what one would need to block on a Windows box in a LAN
environment. For a secure Internet gateway, one of course blocks
everything not needed.)
