RecordTypeEnum (1 byte): A RecordTypeEnumeration value that identifies the record type. The value MUST be 0x00.

RootId (4 bytes):

An INT32 value ([MS-DTYP] section 2.2.22) that identifies the root of the graph of nodes. The value of the field is set as follows.

• If an IsPrincipalMemberOfResponse record is present in the serialization stream, the value of this field MUST contain the ObjectId of the ReturnArray (section 2.3.1.3.1).

Reserved0 (4 bytes): Reserved. MUST be set to 0xFFFFFFFF (-1) and MUST be ignored upon receipt.

MajorVersion (4 bytes): An INT32 value ([MS-DTYP] section 2.2.22) that identifies the major version of the format. The value of this field MUST be 0x00000001.

MinorVersion (4 bytes): An INT32 value ([MS-DTYP] section 2.2.22) that identifies the minor version of the protocol. The value of this field MUST be 0x00000000.
