2.1 Transport

The EFS Group Policy administrative plug-in uses the transport specified in [MS-GPOL] to read and modify settings in the central policy store. Specifically, it uses the file access services protocols described in [MS-FASOD] as the underlying transport for reading, updating, creating, and deleting EFS Group Policy settings. Information is retrieved from the policy store and written to the client's registry by the Group Policy: Registry Extension Encoding ([MS-GPREG] section 3.2) using file access protocols as the underlying transport. The file access version, capabilities, and authentication used for this connection are negotiated between the client and the server when the connection is established.
