You can design a server to allow the coexistence on a host system of multiple
interchangeable instances of a server. Interchangeable server instances are identical,
except for their endpoints; that is, they offer the same RPC interfaces and objects over
the same network (host) address and protocol sequence pairs. For clients, identical
server instances are fully interchangeable.
Usually, for each such combination of mapping information, the endpoint map service
stores only one endpoint at a time. When a server registers a new endpoint for mapping
information that is already registered, the endpoint map service replaces the old map
element with the new one.
