2.2.1.2 Version 2 (RDP_PRECONNECTION_PDU_V2)
The RDP_PRECONNECTION_PDU_V2 extends the RDP_PRECONNECTION_PDU_V1 packet by adding a variable-size Unicode character string. The receiver of this PDU can use this string and the Id field of the RDP_PRECONNECTION_PDU_V1 packet to determine the RDP source. This string is opaque to the protocol.
