<P><FONT SIZE=2 FACE="Arial">I am consistently seeing duplicate packets several microseconds apart. These are always packets being sent by my PC (the one running winPcap). So, I have traffic between the PC and our own device in development. It is a client/server protocol. The PC sends a request, and our device sends a response. However, what I'm seeing is that the PC sends two packets, which is 100% identical (including the IP identification field, and TCP sequence numbers). I highly doubt that both are really making it onto the wire, in the same way that the bogus TCP checksums apparently never made it on the wire.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Has anyone seen this? Does anyone have a theory for why it happens?</FONT>
