I thought that ODBC.dsn didn't work properly because the password(pwd) in the odbc.dsn was encrypted.
So, I found the 'encrypt helper' which encrypts odbc passwords. The 'encrypt helper' can be found in 'GcTools.rar' that you can download at this forum!
However, I don't know how to use it. Since the site '' was cancelled, I couldn't investigate it. (Note that the missing of [ODBC] means the encryption of passwords.)
I tried to make a new ODBC.dsn but it didn't connect the server properly. How did you odbc.dsn revise? In my case, putting 'Trusted_Connection=Yes' seems to work but there remains some errors.
