[Winpcap-users] Size of packet captured!

Standard TDS headers are 4 bytes long.  The first byte is the 'packet type'.  The second byte is the 'last packet indicator'.  The next two bytes are the 'packet size'.  Thus, in your case, you should have gotten a 'packet size' that was greater than one Ethernet packet length (around 1500 bytes).

I suggest you look at: http://www.freetds.org/tds.html
