Description:
------------
Locally on my computer my connection to the database works fine but the moment I upload my file to the web server, and submit a form I receive the error. 

Webserver Information
-----------------------
Operating System: Windows 
PHP Version: PHP 5.x IIS 
Version: IIS 7.0  

code tried but no luck
----------------------
http://us3.php.net/manual/en/function.odbc-connect.php

Reproduce code:
---------------
function connect_to_database($dsn, $user, $password)
{
//create a connection to the database
$conn = odbc_connect($dsn, $user, password,SQL_CUR_USE_DRIVER);
    
   //if the connection failed display the appropriate message
    if(!$conn)
    {
      output_error();
      die();
    }//end if(_);
    else
    { 

     //return connection has been established.
     return $conn;
    }//end else

}//end connect_to_database(_);




Expected result:
----------------
I expected a successful return since every thing on the webserver(Godaddy) is setup correctly according to their test.

Actual result:
--------------
"Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified, SQL state IM002 in SQLConnect in "
