The problem is that i dont use the winpcap library to send packets, i use packet.dll. To be more precise, i use the packetsendpacket function and i pass to it the frame already set up as an array of bytes. I've seen the code of PacketSendPacket and its only an invocation of
kernel32.dll WriteFile function so it should be something with relationship of teh operative system maybe,what do you think? i really need to get this problem solved , can you imagine what could be happening?<br><br>
