How can I restart a windows 2000 machine without getting the "Shut Down Windows" dialog box?

Thanks.
 
I found out how to do it so I thought I'll share it with everyone.

frmReboot (code):

Private Sub Command1_Click()
Call RebootWindows
End Sub

Private Sub Form_Load()
If Command = "-Reboot" Then
Call RebootWindows
End If
End Sub


basReboot (code):

Private Type LUID
UsedPart As Long
IgnoredForNowHigh32BitPart As Long
End Type

Private Type TOKEN_PRIVILEGES
PrivilegeCount As Long
TheLuid As LUID
Attributes As Long
End Type

Private Const EWX_REBOOT = 2

Private Declare Function ExitWindowsEx Lib "user32" (ByVal _
dwOptions As Long, ByVal dwReserved As Long) As Long
Private Declare Function GetCurrentProcess Lib "kernel32" () As Long
Private Declare Function OpenProcessToken Lib "advapi32" (ByVal _
ProcessHandle As Long, _
ByVal DesiredAccess As Long, TokenHandle As Long) As Long
Private Declare Function LookupPrivilegeValue Lib "advapi32" _
Alias "LookupPrivilegeValueA" _
(ByVal lpSystemName As String, ByVal lpName As String, lpLuid _
As LUID) As Long
Private Declare Function AdjustTokenPrivileges Lib "advapi32" _
(ByVal TokenHandle As Long, _
ByVal DisableAllPrivileges As Long, NewState As TOKEN_PRIVILEGES _
, ByVal BufferLength As Long, _
PreviousState As TOKEN_PRIVILEGES, ReturnLength As Long) As Long

Sub AdjustToken()
Const TOKEN_ADJUST_PRIVILEGES = &H20
Const TOKEN_QUERY = &H8
Const SE_PRIVILEGE_ENABLED = &H2
Dim hdlProcessHandle As Long
Dim hdlTokenHandle As Long
Dim tmpLuid As LUID
Dim tkp As TOKEN_PRIVILEGES
Dim tkpNewButIgnored As TOKEN_PRIVILEGES
Dim lBufferNeeded As Long

hdlProcessHandle = GetCurrentProcess()
OpenProcessToken hdlProcessHandle, (TOKEN_ADJUST_PRIVILEGES Or _
TOKEN_QUERY), hdlTokenHandle

LookupPrivilegeValue "", "SeShutdownPrivilege", tmpLuid
tkp.PrivilegeCount = 1 'One privilege to set
tkp.TheLuid = tmpLuid
tkp.Attributes = SE_PRIVILEGE_ENABLED

'Enable the shutdown privilege in the access token of this process.
AdjustTokenPrivileges hdlTokenHandle, False, _
tkp, Len(tkpNewButIgnored), tkpNewButIgnored, lBufferNeeded

End Sub


Public Sub RebootWindows()
AdjustToken
ExitWindowsEx EWX_REBOOT, &HFFFF
End Sub



Have fun testing it :)
