MsgHeader (24 bytes): This field MUST contain a MESSAGE_PACKET structure.
The value of the dwUserMsgType field MUST be 0x00004404.
The value of the dwcbVarLenData field MUST be at least 20.
RecoverySeqNum (4 bytes): A 32-bit signed integer that MUST contain the value for the recovery sequence number of a local LU held by a transaction manager.
Xln (4 bytes): This field MUST contain the log status of a local LU held by a transaction manager. The value MUST be one defined by the DTCLUXLN enumeration.
dwProtocol (4 bytes): A 32-bit unsigned integer that MUST contain 0.
OurLogName (variable): This field MUST contain a DTCLU_VARLEN_BYTEARRAY structure which contains the local log name held by a transaction manager. If cbLength is not a multiple of 4, the end of the field MUST be aligned on a 4-byte boundary by padding with arbitrary values that MUST be ignored on receipt.
RemoteLogName (variable): This field MUST contain a DTCLU_VARLEN_BYTEARRAY structure which either has the cbLength field set to 0, or contains the remote log name supplied by a remote LU. If cbLength is not a multiple of 4, the end of the field MUST be aligned on a 4-byte boundary by padding with arbitrary values that MUST be ignored on receipt.
