    <p>The following code works fine in Visual Studio Development enviroment on my local machine. However when I move the files to a Windows 2008 R2 IIS 7.5 machine I get the following error: </p> <blockquote> <p>[DirectoryServicesCOMException (0x80072020): An operations error occurred. ] _Default.GetFullName(String strLoginName, String&amp; STR_FIRST_NAME, String&amp; STR_LAST_NAME, String&amp; STR_DISPLAY_NAME, String&amp; STR_MAIL, String&amp; STR_OFFICE_PHONE, String&amp; STR_ADDRESS) in c:\AuthTest\Default.aspx.cs:87 _Default.Page_Load(Object sender, EventArgs e) in c:\AuthTest\Default.aspx.cs:23<br> System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +25 System.Web.UI.Control.LoadRecursive() +71 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3064</p> </blockquote> <p>I have Windows Authentication enabled on IIS so I'm not sure if I'm missing something else. Both my local machine and the web server are in the same domain.</p> <p>Here is my code:</p> <pre><code>using System; using System.DirectoryServices; using System.Web.Hosting; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //Gets the extracted User Name using a method. string strUserID = ExtractUserName(User.Identity.Name.ToString()); string STR_FIRST_NAME; string STR_LAST_NAME; string STR_DISPLAY_NAME; string STR_MAIL; string STR_OFFICE_PHONE; string STR_ADDRESS; GetFullName(strUserID, out STR_FIRST_NAME, out STR_LAST_NAME, out STR_DISPLAY_NAME, out STR_MAIL, out STR_OFFICE_PHONE, out STR_ADDRESS); lblHello.Text = "Your User ID is: " + strUserID; TextBox1.Text = "Your name is: " + STR_FIRST_NAME + " " + STR_LAST_NAME + Environment.NewLine + "Display Name: " + STR_DISPLAY_NAME + Environment.NewLine + "Email address: " + STR_MAIL + Environment.NewLine + "Office Phone: " + STR_OFFICE_PHONE + Environment.NewLine + "Address: " + STR_ADDRESS; } //Retrives User Name from DomainName\\UserName private static string ExtractUserName(string path) { string[] userPath = path.Split(new char[] { '\\' }); return userPath[userPath.Length - 1]; } public static string GetFullName(string strLoginName, out string STR_FIRST_NAME, out string STR_LAST_NAME, out string STR_DISPLAY_NAME, out string STR_MAIL, out string STR_OFFICE_PHONE, out string STR_ADDRESS) { string userName = ExtractUserName(strLoginName); SearchResult result = null; using (HostingEnvironment.Impersonate()) { DirectorySearcher search = new DirectorySearcher(); search.Filter = String.Format("(SAMAccountName={0})", userName); search.PropertiesToLoad.Add("cn"); STR_FIRST_NAME = ""; STR_LAST_NAME = ""; STR_DISPLAY_NAME = ""; STR_MAIL = ""; STR_OFFICE_PHONE = ""; STR_ADDRESS = ""; try { result = search.FindOne(); foreach (System.Collections.DictionaryEntry direntry in result.Properties) { STR_FIRST_NAME = result.GetDirectoryEntry().Properties["givenName"].Value.ToString(); STR_LAST_NAME = result.GetDirectoryEntry().Properties["SN"].Value.ToString(); STR_DISPLAY_NAME = result.GetDirectoryEntry().Properties["DisplayName"].Value.ToString(); STR_MAIL = result.GetDirectoryEntry().Properties["mail"].Value.ToString(); STR_OFFICE_PHONE = result.GetDirectoryEntry().Properties["telephoneNumber"].Value.ToString(); STR_ADDRESS = result.GetDirectoryEntry().Properties["streetAddress"].Value.ToString(); } return null; } catch (Exception ex) { throw ex; } } } } </code></pre> <p>Again everything works fine on my local machine in the VS Testing enviroment. I'm probably missing some kind of configuration in IIS?</p> <p>Thanks in Advance.</p>
