Sorry for anoying you chip ! I have buy the book, in the figure 11.6 i don,t understand why the first byte is not 0x02 like explain in the TDS protocol, all documentation i have tell that all communications use the Tabular Data Stream protocol , in this protocol v5.0 we see that the first byte must correspond to 0x02 for the login packet!

I have see the TDS protocol v5.0 at FreeTDS, http://www.ibiblio.org/freetds/tds.html I have read in FoxPro Client Server that every DBMS use TDS but there are multiple TDS protocol proprietary optimized to work exclusively with that DBMS. (Each DBMS can have it proprietary TDS protocol). In your figure 11.6, which one protocol is it ? I want to build a general program that find the login and the password automatically, i need element to find the login and the password in the protocol. The FreeTDS protocol give me what i want cause i know exactly i all case where is the pass, but this protocol is not general !

The capture was from a SQL Server 2000 session so it should be TDS 7.0. What we need is a detailed spec for TDS 7.0 but good luck finding it unfortunately. I will keep my eyes open and do some searching myself. Let's get a thread going since you are definitely doing some interesting work here and getting a better understanding of these protocols is a good ideas all-around. I will keep you posted if I find anything on TDS 7.0.
