<P><FONT SIZE=2 FACE="Arial">I am using the direct Packet interface (e.g. PacketReceivePacket), and I have found that the vast majority of TCP/IP packets being sent out by the PC running packet show up with invalid TCP header checksums. I am running on Windows 2K, SP4 and the interface I am monitoring is a 3COM Ethernet card.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">I am assuming that the invalid checksums are not actually getting out onto the wire, but instead has something to do with when the checksums are computed. Can anyone confirm that this is the case?</FONT></P>
