Hmmm, I think that this is far too broadbrushed anb approach. An in any
case, an API is not an RPC protocol.
An API can be extended to provide access to remote objects transparently
in a couple of ways. One is to use RPC, another is to build a protocol
that allows each of the operations to be sent over the wire. SMB is
pretty much like the latter. After a while MS and the others who worked
on SMB got pretty sick of adding new SMB types whenever they needed to
do something more, so they started adding transact and transact2 calls.
However, they got pretty sick of that too, and added RPC on top.
A hallmark, I think, of an RPC system is that you don't have to add more
protocol types (SMBs) to extend access to more objects/functions on the
remote system, you simply add more definitions to your IDL file and
I contend that SMB is not (an) RPC (protocol), it is simply a remote
access protocol. MS have, however, used SMB as a transport for their RPC
mechanism, which is DCE/RPC.
