Is there a way to see the value with tcpdump? I only control the 
firewalls and did a "tcpdump -X -s 0", I'll investige more time on this 
with wireshark.

See above, client and server (both Windows) is not under my control. 
I'll let my client install wireshark on the server and check firewall 
settings.
