Thread context of SYN packet and TdiConnect

Hi,
Am I correct in assuming that a TCP/IP SYN packet is not
necessarily sent in the same thread context as the thread that
called TdiConnect?

Yes. For example if you do not have an ARP entry for the IP address you are
connecting, the system has to do an ARP. After the IP address is resolved
the actual IP packet is sent. There can be other situations like IMdriver is
layered between you and Tcpip and the driver or NDIS is doing packet Qing.

You cannot make any assumptions about in what thread context the
NDIS-level packet is sent.
