Hi Mike Horton!

I have configured according to your instructions but it still the same error.

I also tested it with an aspx page that has been connected to the domain.

This is aspx page:

 DirectoryEntry entry = new DirectoryEntry("LDAP://nvkiet.com",
                                                   "administrator",
                                                     "nvkiet");

            Object obj = entry.NativeObject;
            DirectorySearcher search = new DirectorySearcher(entry);
            search.Filter = "(SAMAccountName=administrator)";
            search.PropertiesToLoad.Add("cn");
            SearchResult result = search.FindOne();

         if (null == result)
            {
                Label1.Text = "connec error";
            }
            else
            {
                Label1.Text = (String)result.Properties["cn"][0];
            }

It is currently unknown what errors in configuration or not?

We hope to help you.

Thank you.
