enumeration and MS DCERPC

Enumeration, enumeration, and even more enumeration is the generic pentesting mantra, but enumeration is worthless if you can't read the results.

I came across the Windows RPC service, where metasploit returns results such as

msf auxiliary(endpoint_mapper) > run

However, I have no idea what to do with this information. Sample #1 seems to be kind of useful, but anyway: How would this information help an attacker to plan his next move? What is metasploit telling me here?
