I think the question is how to access a database on a different machine, if that is the case – you can specifiy the IP address or name of the remote machine in the connection string:

public SqlConnection Conectar(string remoteMachine)
{
      SqlConnection con = new SqlConnection(string.Format(@"Data Source={0}\sqlexpress;Initial Catalog=misnotas;Integrated Security=True", remoteMachine));
      return con;
}

Note however you still have to figure out security, i.e. integrated security might not work remotely – for a full list of the options with examples check out this link.
