Hi. When NBSS session or session smb occurs in the middle of the TCP packet, I can not see them properly in wireshark.alt text How do I can see the analysis of these protocols, if they are in the middle of the tcp packet? I tried to do it using the menu "Decode as...", but nothing happened.!

Working from a screenshot is prohibitively difficult. Can you share a capture in a publicly accessible spot, e.g. CloudShark?

I moved your "answer" to a comment under the question when you posted it and then deleted the 2nd "answer" as it was a duplicate.

Please read the site FAQ for more information.

Currently, no. Wireshark would have to scan through the packet to find the beginning of the SMB2 message (which actually beings with the "NetBIOS SS" data - Wireshark really should be labeling port 445 traffic as SMB, not NBSS, as SMB-over-TCP uses something similar to, but simpler than, NBSS), show the data before it as continuation data, and show the SMB2 message. It currently doesn't do that.

It'd be a lot easier to test and implement it if we had a capture file, just as Jaap suggested.
