    You are using ODBC to connect to the server. You have to make sure that if you use a DSN (named ODBC connection that is stored on the server) that you create it on the server this code is running on. If you use a DSN-less connection (you do the setup in your code), you need to make sure the ODBC driver you are using is installed on the server.

    A DSN-less connection string might look like this:

    Driver={SQL Native Client};Server=myServerAddress;Database=myDataBase; Trusted_Connection=yes;

    Not all of them specify a driver but in this case it does. You would need to make sure that the “SQL Native Client” driver was installed on your server. A DNS connection would have a DSN entry in this string instead, like so:

    DSN=MyDBConnection;

    Look through your code and you will find out which you have. Once you find that out, find out what you need to put on the server. Most likely you need to add a DSN to the server. This is done by going to the Control Panel and searching for ODBC. Once you are there, you can create a new ODBC entry that matches the one on your development machine. Here is a link on creating an ODBC (DSN) entry:

    http://support.microsoft.com/kb/305599

    Make sure you create a DNS under the System, not the User tab. That way, it is available for any login the application might run under.
