登錄失敗：未知用戶名或密碼錯誤。訪問其他服務器時出錯

Question

我正在使用登錄憑證訪問其他服務器。我的問題是，如果我最初運行的代碼，它西港島線顯示誤差

Logon failure: unknown user name or bad password 

但如果我嘗試通過在命令提示符下連接到服務器一次之後運行的代碼。然後，應用程序正常工作，它不會引發任何錯誤。所以，每天我都需要通過命令提示符連接到服務器一次，以便無誤地運行應用程序。

這裏是我的代碼：

static void main() 
{ 
    string sourceDir = "//server.domain.mhc//drive"; 
       string DestinationDir = "D:\\Test"; 

       DirectoryCopy(sourceDir, DestinationDir, true); 
} 

[DllImport("advapi32.DLL", SetLastError = true)] 
public static extern int LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken); 

private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs) 
{ 
    clsEmail objEmail = new clsEmail(); 
    try 
    { 
     IntPtr admin_token = default(IntPtr); 
     if(LogonUser("myusername","domain","pwd",9,0,ref admin_token) != 0) 
     { 
      DirectoryInfo dir = new DirectoryInfo(sourceDirName); 
      DirectoryInfo[] dirs = dir.GetDirectories(); 
     }

發現瞭解決方案。查看答案的更新代碼。

try 
    { 
     IntPtr admin_token = default(IntPtr); 
     //Added these 3 lines 
     WindowsIdentity wid_current = WindowsIdentity.GetCurrent(); 
     WindowsIdentity wid_admin = null; 
     WindowsImpersonationContext wic = null; 


     if(LogonUser("myusername","domain","pwd",9,0,ref admin_token) != 0) 
     { 
     //Newly added lines 
     wid_admin = new WindowsIdentity(admin_token); 
     wic = wid_admin.Impersonate(); 

     DirectoryInfo dir = new DirectoryInfo(sourceDirName); 
     DirectoryInfo[] dirs = dir.GetDirectories(); 
     } 
    }
