In your Windows -> Samba trace, it's packet number 14 (Tree Connect Response).

Expand that packet out with wireshark and you'll see at the end
of the reply.

Access Mask: 0x001f00a9

If this share should be read-write, pick an appropriate
user that exists on the server with read-write access to
that data. As I don't know anything about your setup,
that's the only advice I can give.

Avoid "guest" with SMB2+ if you can.
