Thanks for this suggestion, but since I am noob in this respect, can you
explain me how I can look at this?
And what's the UG (and its tenderfood section)?

I have thought that maybe I could need dboption()'s but I didn't manage to
find a help about what options to set, how and what is their meaning.

Looking slightly more in detail, I found that the login packet sent by my
application to that server is an XML block (since I am not  the owner of
the credentials I hide them):

<EVENT_INSTANCE><EventType>LOGON</EventType><PostTime>2012-09-20T15:43:17.147</PostTime><SPID>385</SPID><ServerName>[...]</ServerName><LoginName>[...]</LoginName><LoginType>SQL
Login</LoginType><SID>[...]</SID><ClientHost>192.168.235.238</ClientHost><IsPooled>0</IsPooled></EVENT_INSTANCE>

...and it could be possible that the server does not like or is not well
configured to accept messages like them, but I didn't ever tell my
implementation to communicate in XML, and then I don't know if there are
other possibilities (and which one is used by "tsql" executable), and how I
can eventually switch among them.

Thanks a lot and best regards.

Alberto
