  Start off by reviewing this: http://dynamicsuser.net/blogs/navdev/ar ... rvice.aspx. It shows the general case for how to consume a Nav 2009 web service from C#.
  
  The question you seem to be focusing on is with authentication to the web service - I'm guessing you're getting a HTTP 401 unauthorized error, or something similar.
  
  There are two options here:
  
  1. Set your C# application to run in the context of the user that has permissions on the web service, then use the

  NavWebService.usedefaultcredentials = true;
  

  setting shown in the article referenced above.
  
  However, if you're running on a mobile device, #1 could be tricky. So let's look at option #2
  
  2. Get rid of

  NavWebService.UseDefaultCredentials = true;
  

  and use this in its place:
  

  NavWebService.UseDefaultCredentials = false;
  NavWebService.Credentials = new NetworkCredential("myUsername", "myPassword");
  

  
  I think the NetworkCredential constructor also takes your domain name as a third parameter if needed.

  Thanks for that Tim
  
  I have tried doing what you suggested, but I am still unable to get a connection.
  
  I am using the following code extracted from Lars Lohndorf-Larsen's example
  

  using System;
  using System.Linq;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Data;
  using System.Drawing;
  using System.Text;
  using System.Windows.Forms;
  using System.Reflection;
  using System.Net;
  
  namespace SmartDeviceProjectLars
  {
      public partial class Form1 : Form
      {
          public Form1()
          {
              InitializeComponent();
          }
  
          private void button1_Click(object sender, EventArgs e)
          {
              WS.web NAVWebService = new WS.web();
  
              NAVWebService.Credentials = new NetworkCredential("Name", "Pass");
  
              textBox2.Text = NAVWebService.AddX(textBox1.Text);
  
  
  
          }
      }
  }
  

  
  Because it is a smart device project "NavWebService.UseDefaultCredentials = false" is not available.
  
  I have used the identical code in a windows application and it works perfectly.
  
  Any other suggestions?

  I was using an emulator from visual studio to test this.
  I have since copied the exe file to a mobile device and it is now working OK
  
  Thanks for your help
