------- Comment #1 from gerard.gatineau at laposte.net  2006-07-09 14:56 CET -------
New test with modification of NDIS "Debug_Packet" output to match Ethereal one

0A 2F 00 F8 = Ros PC IP address
CA 86 AO 07 = DNS IP address
51 FF 36 08 = IP adress of POP server www.laposte.net

Conclusion : No SYN+ACK received from Pop server with ROS

1) DNS Query
