3.1.5.2 Policy Administration Delete Message Sequencing

To delete the policy settings in a GPO using administrative tool plug-ins, the state of that GPO on the Group Policy server MUST be updated with a new preferences policy message. This MUST be accomplished by using the following message sequence:

  1. SMB file open from client to server:

    The file name used MUST be a path defined in section 2.2.1, and be specific to each preference type, where <gpo path> is the user-scoped GPO path if the GPO's user settings are being updated or if the computer-scoped GPO path of the computer settings is being updated.

    The SMB file open MUST request write permission.

    If the open request returns a failure status, the Group Policy: Preferences Extension sequence MUST be terminated.

  2. SMB file delete sequences:

    The administrative add-in MUST perform a series of SMB file writes to delete the contents of the opened file.

    If an error is encountered, the protocol sequence MUST be terminated.

  3. The administrative tool invokes the task Group Policy Extension Update ([MS-GPOL] section 3.3.4.4).
