Hi João

As far as I know, that kind of connection (via ODBC, with DRIVER={SQL Server}) uses integrated security by default, unless you specify a UID / PWD
And in any case, "Trusted_Connection=Yes;" would do the job.

Why don't you try the OLEDB connection string:

o.Open("Provider=SQLOLEDB;Data Source=(local);Initial Catalog=Northwind;Integrated Security=SSPI")

(At least try it to verify if the current user really has the required permissions, if you don't want to switch permanently to the OLEDB provider)
Maybe your code is executing with another identity (i.e. Anonymous user on an ASP page)

Hope this helps
