or try this one : using System; using System.Runtime.InteropServices; namespace Reboot { /// /// Defines constants and API calls for rebooting XP. /// class XPReboot { [StructLayout(LayoutKind.Sequential Pack=1)] internal struct TokPriv1Luid { public int Count; public long Luid; public int Attr; } [DllImport(kernel32.dll ExactSpelling=true) ] internal static extern IntPtr GetCurrentProcess(); [DllImport(advapi32.dll ExactSpelling=true SetLastError=true) ] internal static extern bool OpenProcessToken( IntPtr h int acc ref IntPtr phtok ); [DllImport(advapi32.dll SetLastError=true) ] internal static extern bool LookupPrivilegeValue( string host string name ref long pluid ); [DllImport(advapi32.dll ExactSpelling=true SetLastError=true) ] internal static extern bool AdjustTokenPrivileges( IntPtr htok bool disall ref TokPriv1Luid newst int len IntPtr prev IntPtr relen ); [DllImport(user32.dll ExactSpelling=true SetLastError=true) ] internal static extern bool ExitWindowsEx( int flg int rea ); internal const int SE_PRIVILEGE_ENABLED = 0x00000002; internal const int TOKEN_QUERY = 0x00000008; internal const int TOKEN_ADJUST_PRIVILEGES = 0x00000020; internal const string SE_SHUTDOWN_NAME = SeShutdownPrivilege; internal const int EWX_LOGOFF = 0x00000000; internal const int EWX_SHUTDOWN = 0x00000001; internal const int EWX_REBOOT = 0x00000002; internal const int EWX_FORCE = 0x00000004; internal const int EWX_POWEROFF = 0x00000008; internal const int EWX_FORCEIFHUNG = 0x00000010; private static void RebootDialer(int flg) { bool ok; TokPriv1Luid tp; IntPtr hproc = GetCurrentProcess(); IntPtr htok = IntPtr.Zero; ok = OpenProcessToken( hproc TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY ref htok ); tp.Count = 1; tp.Luid = 0; tp.Attr = SE_PRIVILEGE_ENABLED; ok = LookupPrivilegeValue( null SE_SHUTDOWN_NAME ref tp.Luid ); ok = AdjustTokenPrivileges( htok false ref tp 0 IntPtr.Zero IntPtr.Zero ); ok = ExitWindowsEx( flg 0 ); } static void Main() { RebootDialer(EWX_REBOOT + EWX_FORCE); } } }
