The code below works when I point it to two of my three SharePoint servers.  My third server I get 401 error.  Any ideas anyone ?

    private void button3_Click(object sender, EventArgs e)
      {
        label3.Text = "";
        try
        {
          treeview1.Nodes.Clear();
          ClientContext clientContext = new ClientContext(comboBox1.Text);
          Web oWebsite = clientContext.Web;
          ListCollection collList = oWebsite.Lists;
          clientContext.Load(collList);
          clientContext.ExecuteQuery();
          foreach (SP.List oList in collList)
          {
            TreeNode listnode = new TreeNode();
            listnode.Text = oList.Title;
            treeview1.Nodes.Add(listnode);
          }
        }
        catch (Exception ex)
        { label3.Text = ex.Message; }
      }

Are you using Kerberos?

I've heard of this one but happily not experienced it myself. Incorrect Kerberos config causing custom code to fail authentication on one WFE but not others.

These are the closest resources I can find to addressing this;

Through reading these articles I installed Fiddler, and watched my transaction.  Something about the hostname looked odd to me so I used IP address instead.  Code now works.  The hostname of course works when you put it in a browser, but not in my code.  

"http://sp1" is a browsable sharepoint server, but this line doesn't like it:
ClientContext clientContext = new ClientContext(comboBox1.Text);

I am having my server team put in a nice DNS entry for the server.
