2.1 Transport
The Group Policy: Central Access Policies Extension requires remote access to policy files, as specified in [MS-GPOL] section 2. All messages specified in section 2.2 of this specification MUST be exchanged via a file access protocol between the Group Policy client and Group Policy server and between the Administrative tool and the Group Policy server, assuming that the Group Policy file share is located on the Group Policy server ( section 1.3). <2>
The core Group Policy engine MUST use this protocol's CSE GUID and Administrative tool extension GUID values to invoke the client or administrative side of this protocol, respectively, which in turn invoke LDAP to access GPOs that require processing by this protocol.
