Are you sending the packet out using Winpcap or are you using a tcp/ip socket? Sockets will add TCP and IP headers to any info you send via them. Have you tried the PacketSendPacket() function? Can you capture the packet you send out using your sniffer? It should appear on the wire just like the first packet you capture.
