Problems with ODBC 3.51 driver

[T C]

I must access a MySql database out of ASP.NET. As I understood, ODBC is the most used technology for this task (?)

I downloaded "MySQL ODBC 3.51 driver."

Stupid question: I installed this driver on my local developer PC and not on the server in our network, where the MySQL-DB is running.
Is this right or wrong ?!

I wrote the following code:

class Program
{
static void Main(string[] args)
{
const string ConnStr = "Driver={MySQL ODBC 3.51 Driver};" +
"Server=192.<*******>;" +"Port=3306;"+
"Database=theo;" +
"User=root;" + "Password='';" + "Option=3";

using (System.Data.Odbc.OdbcConnection connection =
new System.Data.Odbc.OdbcConnection())
{
connection.ConnectionString = ConnStr;
connection.Open();
connection.Close();
}
}
}



Compiling goes without error, but when starting the code, I get the error:

ERROR [HY000] [MySQL][ODBC 3.51 Driver]Host 'THEO' is not allowed to connect to this MySQL server

The MySQL-DB has no passwords set.
