Hi everybody,
 Please look at this code, the rebooting/reset does not happen. Waht is
wrong with this code?
How to fixed this?

Code:
[StructLayout(LayoutKind.Sequential, Pack=1)]
private struct Luid //change to internal public accessor not working
{
  public int Count;
  public long pLuid;
  public int Attr;
}

const int SE_PRIVILEGE_ENABLED = 0x2;
const int TOKEN_QUERY = 0x8;
const int TOKEN_ADJUST_PRIVILEGES = 0x20;
const int EWX_REBOOT = 0x2;
const int EWX_FORCE = 0x4;
const string SE_SHUTDOWN_NAME = "SeShutdownPrivilege";

[DllImport("advapi32.dll", ExactSpelling=true, SetLastError=true)]
internal static extern bool AdjustTokenPrivileges(IntPtr htok, bool
disall,ref Luid newst, int

len, IntPtr prev, IntPtr relen);

[DllImport("user32.dll")]
static extern int ExitWindowsEx(int uFlags, int dwReason);

private void ActivatePrivileges()
{
   Luid uID;
   IntPtr ptrProcess = Process.GetCurrentProcess().Handle;
   IntPtr ptrToken = IntPtr.Zero;
   //Need to adjust the priviledge in order to shut down...
   OpenProcessToken(ptrProcess, TOKEN_ADJUST_PRIVILEGES / TOKEN_QUERY,
ptrToken);
   uID.Count = 1;
   uID.pLuid = 0;
   uID.Attr = SE_PRIVILEGE_ENABLED;
   LookupPrivilegeValue(null, SE_SHUTDOWN_NAME, uID.pLuid);
   AdjustTokenPrivileges(ptrToken, false, uID, 0, IntPtr.Zero,
IntPtr.Zero); //Error Occurs

here
}

//Executing inside
private void btnReset_Click(object sender, System.EventArgs e)
{
   ActivatePrivileges();
   ExitWindowsEx(2, 0);//This does nothing
}
