[MS-DFSRH]: DFS Replication Helper Protocol Specification

The client sends the server the information about the Active Directory operation that it is trying toaccomplish. The server then attempts to execute the command by using the machine account andreturns information about the status of the operation.The second part of the Distributed File System: Replication Helper (DFS-R Helper) Protocol is aninterface for monitoring DFS-R on the computer and collecting various statistics about the DFS-Roperation.The information that is collected by using the Distributed File System: Replication Helper (DFS-RHelper) Protocol includes, among other types of information, the following statistics:• Information about replication errors that are encountered by DFS-R on the server.• The count and size of replicated files on the server.• Disk use on the server.• Information about replicated folders on the server.• Replication backlog—the number of files that are not yet fully replicated.Sections 2 and 3 specify the Distributed File System: Replication Helper (DFS-R Helper) Protocol anddefine protocol messages, their parameters, and the XML format of the health report.1.4 Relationship to Other ProtocolsThe Distributed File System: Replication Helper (DFS-R Helper) Protocol relies on the DistributedComponent Object Model (DCOM) Remote Protocol (as specified in [MS-DCOM], which uses RPC asits transport. For more information, see [MS-RPCE].1.5 Prerequisites/PreconditionsThis protocol is implemented over DCOM and RPC. Therefore, it has the prerequisites that arespecified in [MS-DCOM] and [MS-RPCE] as common to the DCOM and RPC interfaces.The Distributed File System: Replication Helper (DFS-R Helper) Protocol assumes that a client hasobtained the name of a server that supports this protocol suite before the protocol is invoked.1.6 Applicability StatementThis protocol is applicable when an application needs to modify the DFS-R configuration by using thecredentials of the server computer. The client also uses this protocol to get health information forthe DFS-R service on the remote server.1.7 Versioning and Capability NegotiationSupported Transports: This protocol MUST use the Distributed Component Object Model (DCOM)Remote Protocol (as specified in [MS-DCOM]), which in turn uses RPC over TCP, as its onlytransport, as specified in section 2.1.Protocol Version: This protocol includes three DCOM interfaces, all of which are version 0.0. Aclient MUST use one or more of the following interfaces when it communicates with a Distributed FileSystem: Replication Helper (DFS-R Helper) Protocol server:• IADProxy• IADProxy2[MS-DFSRH] – v20080207DFS Replication Helper Protocol SpecificationCopyright © 2008 Microsoft Corporation.Release: Thursday, February 7, 20089 / 81
