Michael, Just done a bit more googling and reading. Certainly this Microsoft customer service engineer thinks that a lot of problems are caused by Large Segment Offload - http://blogs.msdn.com/b/psssql/archive/2010/02/21/tcp-offloading-again.aspx There may be some value in turning this off, assuming it is on (at least for a test) and seeing whether Wireshark starts behaving and your application as well.
While trying to sort out TCP packets not reaching a target on the other side of multiple firewalls we found we had to turn off LSO and TCP chimney. Until we did that Wireshark saw only SYN, FIN and RST packets. Since we haven't seen any noticable performance degradation, we have not turned them back on.
