Windows Process Description:

The rpcrt4.dll module, commonly referred to as the Remote Procedure Call (RPC) run-time library, contains the routines, tables, and data that support communication between clients and servers. It is used by Windows to send and receive RPC requests.

The RPC tools make it appear to users as though a client directly calls a procedure located in a remote server program. It uses the client/server model in which the client is the requesting program and the server is the service-providing application. The client and server each have its own memory resource allocated to data used by the procedure.

The file rpcrt4.dll contains client routines, server routines, and others that both clients and servers can use. RPC run-time routines are responsible for transmitting RPC packets between the client and server stubs.

The Remote Procedure Call is like a function call. The calling arguments are passed to the remote procedure and the caller waits for a response to be returned from the remote procedure. It is a protocol that one program can use to request a service from a program located in another computer in a network without having to understand network details

The rpcrt4.dll file also provides two routines that convert between names and socket addresses. These routines enable programs to use names rather than addresses to identify server hosts.

The RPC is a powerful technique for constructing distributed, client-server based applications. It is based on extending the notion of local procedure calling, so that the called procedure need not exist in the same address space as the calling procedure. The two processes may either be on the same system or on different systems with a network connecting them. By using the rpcrt4.dll file, programmers avoid the details of the interface with the network.
