Is it possible to turn impossible to shutdown the computer with the front switch button?
This machine is a domain controller and it's very important to be on, and sometimes it's switch off by some kicks :p
There are any way to turn this possibility off?
 
which os are you using?

if you are using XP, then there's options for the power switch you can set, and these include prompt/ignore or something similar...

I don't think there's anything from other versions of windows, and not sure about linux/whatever, so ur probably gonna have to physically disconnect the wire in those cases...

Procrastinate Now!
 
But turning off the wire, doesn't imposibilitate me to turn on the computer when i turn it off?
 
You might be able to put the switch in the back, or rig one switch lead to go through a set of NC points of a small relay powered by the PS.

Give the wrong symptoms, get the wrong solutions.
 
Check your in motherboard manual. There may be a jumper that you can set such that the power-on is always "on", regardless of the front switch, and then you control it from the power supply switch from the back of the computer. If it is present, then you can unplug the front switch from the motherboard, as keeping it there can still trigger other events like power management.
If the motherboard has no such jumper, you can still do something if not far from you there's a technician who can correctly connect wires. On the ATX power connector, the green wire (pin 14) is the power-on signal. To turn on you need to ground this pin i.e. short it to one of the black wires.

 
Cover the switch with a bottle cap and some tape? Maybe not the prettiest sight, but far easier to implement...
 
If you do it with the bottlecap, then put a parallel switch in the back.

There isn't any professional way to this? :p
At least there isn't a way to windows ask the user if he really want to shutdown? It seams to me that that "$#?"(%# button isn't so pratical at all...
 
As you've not yet stated what your OS is, everybody's shooting in the dark. Crowley16 suggested that XP's power options offer a solution, and if you have XP you should indeed go to the Advanced Tab of the Power Options Properties in the Control Panel.

Otherwise, try the bottle cap.

Sloth is the mother of invention. Necessity is just a mother...
 
I'm sure my home machine has something in the BIOS that covers this. You can change it so that you have to press and hold the power button for a second or two to turn it off. It's a Gigabyte GA7VA motherboard.

Here's another idea: PUT YOUR DOMAIN CONTROLLER IN A PLACE WHERE IT WON'T ACCIDENTALLY BE KICKED! If you absolutely cannot put it out of reach of human feet, face it against the wall, or a corner.
 
They make computer cases with the button inside a door that is locked that protects the drives. You could also get an extra on switch and mount it on the back of the case or wire the on switch to the reset switch if it is harder to press. I know some computer cases no longer use a reset switch, but I have used one for the power on switch before.

If you do not like my post feel free to point out your opinion or my errors.
 
Since a case's reset button is often recessed much further than the power button (and thus harder to kick), on occasion I've wired the reset switch as the power switch and left the power button unconnected.

A "professional" way to do it would be to get a momentary contact switch from Radio Shack or the like, drill a hole in the back of the case, mount the switch, and wire it to the power on leads on the motherboard and leave the front switch unconnected.
