在生產時出現Directory.Services錯誤

Question

以下代碼在本地計算機上的Visual Studio Development環境中正常工作。然而，當我將文件移動到Windows 2008 R2的IIS 7.5的機器，我得到以下錯誤：

[DirectoryServicesCOMException (0x80072020): An operations error occurred. ] _Default.GetFullName(String strLoginName, String& STR_FIRST_NAME, String& STR_LAST_NAME, String& STR_DISPLAY_NAME, String& STR_MAIL, String& STR_OFFICE_PHONE, String& STR_ADDRESS) in c:\AuthTest\Default.aspx.cs:87 _Default.Page_Load(Object sender, EventArgs e) in c:\AuthTest\Default.aspx.cs:23
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

我有IIS中啓用Windows身份驗證，所以我不知道如果我失去了別的東西。我的本地機器和Web服務器都在同一個域中。

這裏是我的代碼：

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; 
       } 

      } 
     } 
} 

再次一切正常我的本地計算機上的測試VS環境。我可能在IIS中缺少某種配置？

在此先感謝。

首先要檢查IIS應用程序池標識是否具有對AD的正確權限。
