lukor have offered to help in analyzing the issue so I'd rather wait for their support about the correct way in performing the packet capture and the tool to adopt (as I said I am not too into developing stuffs).
I have taken a look on the site you suggested but seems that their tool is not the best as far as winXP is concerned:
"The current version of Wireshark should support any version of Windows that is still within its
extended support lifetime. At the time of writing this includes Windows 10, 8, 7, Vista, Server 2016,
Server 2012 R2, Server 2012, Server 2008 R2, and Server 2008."
