 Hi David,

 I had tried this and it worked / works:

Microsoft OLE DB Provider for ODBC Drivers (0x80004005) [Microsoft][ODBC SQL Server Driver][SQL Server]Error de inicio de sesión del usuario 'sa'.

Error msg is in Spanish but it seems ok: it tries to login with 'sa' user but the password isn't correct. My question was about how to automatize this.

 Is there any form of SQL script that could be injected to perform the brute force attack? I mean, I'm looking for some kind of semi-complex SQL sentence which should generate character combinations becoming a new possible password, and then it should try to use the password in a sentence like the one you submitted. The script must be executed locally in the victim server, through SQL injection hole.

Do you need help?
