2.1 Transport

The Group Policy: Security Protocol Extension SHOULD<1> transport messages (in the form of files) over the Group Policy Protocol over the Server Message Block (SMB) Versions 2 and 3 Protocol, as specified in [MS-SMB2]. The client-side plug-in MUST use this protocol's CSE GUID (as specified in [MS-DTYP] section 2.3.4), and the administrative-tool plug-in MUST use the tool extension GUID.

The Group Policy: Core Protocol uses this protocol's CSE GUID and tool extension GUID values (see section 1.9) to invoke this protocol only to access GPOs that require processing by this protocol.
