RPC Can Use Multiple Protocols

Article ID: Q100009
Creation Date: 14-JUN-1993
Revision Date: 02-NOV-1995 The information in this article applies to:

  • Microsoft Win32 Software Development Kit (SDK) versions 3.1, 3.5, and 4.0

Microsoft Remote Procedure Call (RPC) does not rely on a single protocol. An RPC server can be written to use all available protocols on the server, and a client can be written in the same manner. Thus, the server or client does not have to know which protocols it supports explicitly.

RPC protocols supported by Windows 3.1 and 3.5 are:

   ncacn_ip_tcp   (TCP/IP)
   ncacn_nb_nb    (NetBIOS over NetBEUI)
   ncacn_nb_tcp   (NetBIOS over TCP)
   ncacn_np       (Named Pipes)
   ncalrpc        (LPC)

RPC protocols supported by Windows 3.5 only are:

   ncadg_ipx      (Datagram - IPX)
   ncacn_spx      (SPX)
   ncadg_ip_udp   (Datagram - UDP)
   ncacn_nb_ipx   (Netbios over IPX)

RPC protocols supports by Windows 95 are:

   ncacan_ip_tcp
   ncacn_nb_nb
   ncacn_np
   ncacn_spx
   ncalrpc
