1 Introduction

This is a protocol document specifying the File Replication Service (FRS) Protocol. The FRS Protocol is used to replicate files and folders among servers on the network. This protocol enables duplicate files and folders to be maintained on multiple servers. Microsoft operating systems use FRS to maintain duplicate copies of data files in system volume (SYSVOL) system folders on multiple domain controllers in a domain. Microsoft operating systems also use FRS to replicate data files among Distributed File System (DFS) shares.

This document provides detailed technical reference material for the Remote Procedure Call (RPC) interfaces, packet formats, and data structures required for interoperation using FRS.

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
