how do i disable "It is now safe to turn off your computer" closing screen?

What version of windows are you using?  how old is the physical hardware?

It's a new Dell, Windows XP.  What I mam trying to do is shutdown a bunce of Dell computers remotely.  The other machines that have been here shutdown fine with the remote setup, but the Dell show that message.  So you have to shut them all off by hand.

Make one of these shortcuts on each computer and then call them remotely

"
1.) Shutdown shortcut: The first step to a your one click shutdown shortcut button, is to right-click on your desktop, now choose New, then choose Shortcut. The Windows Shortcut Wizard will appear. In the box that appears, in the "location of shortcut area" type in shutdown -s to shutdown. For the name leave it shutdown or type in a new name like SHUTDOWN or OFF.
"
shutdown -f will forces any running applications to shot down  <-- could be useful

Oh just realized what you mean... not sure if the shortcut method will work better then what you had before then.

sorry there >.<

"It is now safe to turn off your computer"  ; That's regular message on older Pentium I systems with old power management specification Advanced Power Management and ACPI (Advanced Configuration & Power Interface version 1.0 )
      
Open your " new Dell, Windows XP " PC  BIOS and make sure ADVANCED POWER MANAGEMENT is  ENABLED.
If it's not , enable it and restart computer. Let Windows XP to fully load GUI and after minute or two try to shutdown system.
See what happens.
If the problem persists try to flush your computer BIOS ( it might be corrupt) . NOTE :flushing the BIOS is very sensitive and critical procedure. Read carefully Dell's system documentation, look for Dell's tech support WEB sites for issues they have with your computer model and update the BIOS if necessary.
Also problem might be related to your systems power supply - somehow it wont release the power so you have to do it manually.
If it's new cpomputer still under warranty I wouldn't  hesitate to make phone call to their tech support.

good luck

All the machinses are the same.  They all display the "message" when I remotely shutdown.  So I don't think it is a defect or problem with the machines.  I have seen this problem before in XP but I can't remember how to fix it.  I checked the power settings in the BIOS and nothing references ADVANCED POWER MANAGEMENT so I am at a standstill.  I thank all of you for the responses.  Unfortuneately, none of them are hitting the problem.

if they are the same model, post the model here, then we can look further

I don't know what you mean by model and  "post the model here".  

what model of PC you have (not your car !)

          All right , it may or may not read Advanced Power Managhtement exactly but there must be an option screen for power management in your systems' BIOS-es.

"In order to use the ACPI power management features in Windows XP Professional, your computer must have an ACPI-compliant BIOS that is compatible with Windows XP Professional.
During setup, Windows XP Professional determines which hardware abstraction layer (HAL) to install on the computer. If the computer has an ACPI-compliant BIOS, an ACPI HAL is installed and you are able to use ACPI power management features. If the computer does not have an ACPI-compliant BIOS, a non-ACPI HAL is installed and ACPI power management features are not available."
http://www.microsoft.com/resources/documentation/Windows/XP/all/reskit/en-us/Default.asp?url=/resources/documentation/Windows/XP/all/reskit/en-us/prdc_mcc_htev.asp
        To determine whether Windows XP Professional is running in ACPI mode
   1. In Control Panel, click Performance and Maintenance, and then click System.
   2. In the System Properties dialog box, click the Hardware tab, and then click Device Manager.
   3. In the details pane, click Computer.
        If Advanced Configuration and Power Interface (ACPI) PC is listed under Computer, the computer is operating in ACPI mode.
------------------- or ---------------------
To determine if your computer was detected as being ACPI enabled:

Right click My Computer then click Properties > Hardware > Device Manager.
Expand the entry called Computer.
If the entry is 'Advanced Configuration and Power Interface (ACPI) PC' you're all set. If it says 'Standard PC' the computer BIOS was not detected as being ACPI capable.

I would also recommend you to check your network card status and make sure they are not configured in way that is preventing OS from shuting down.

P.S.
It would be really great if you can provide your computer model code ( Latitude, Dimension ,Inspirion , Precicion M60, OptiPlex 160L and so on ) so we can determine the issue better.

The machines are Dell Optiplex GX520.  I went into the Device Manager and clicked on Computer and saw that is said "ACPI Multiprocessor PC". Also, there is no Power and Mantenance choice in Comntrol Panel in this version of Windows XP, in fact, I have looked at three different macines all differnt brands and none of t hem have that option on them.  What they do have is a Power Options choice which does  not do much.  I also went into the BIOS and found a Power Management category which had the following choices, none of which had anything to do with what you guys are talking about.  Here are the choices:
AC Recovery, Auto Power ON, Auto Power Time, Low Power Mode, Remote Wake Up, Suspend Mode.

Go to Control Panel -> Power Options -> APM / Advanced Power Management -> Turn on the 'Enable Advanced Power Management' Option.

If this option isn't there, your HAL may not be updated to recognize/support APM. You may also need to ensure that any APM or APM-aware OS options are enabled in the BIOS.

Hope that helps!

It isn't there.  As you can see from my last entry there is nothing in the power managagement section of the BIOS that refers to HAL.  Where else would it be?

still having problem with this shut down  have tried everything you suggest but still cant get the message its safe to turn of pc of the screen any ideas?
