How do I avoid a remote FTP server error 451 ?

Hi;

I am trying to get a directory list from an FTP server.

I can log on to the server through IE 6.0.

But when I try this via a program I get "The remote server returned an error (451) local error in processing"  message.

Here is the code I am using :

  

 Imports System

Imports System.Collections.Generic

Imports System.Reflection

Imports System.Net

Imports System.IO
