When I try to do it by pressing the shortcut key it trurns lowest brightness level and I can only fix by pressing the patch at the start of the laptop. I can't go back to the old version of the bios. What should I do? can anyone help please. Thank you

  Hi Tom,

  A firewall is software or hardware that checks information coming from the Internet or a network. The firewall blocks the information or allows information to pass to your computer. If the information is blocked or passed through depends on your firewall settings. A firewall can prevent malicious software (such as worms) to access your computer through a network or the Internet. A firewall can also help stop your computer from malware sent to other computers. Windows XP, Windows XP SP2 and Windows XP SP3 includes firewall software.

  Perform the steps from the link below and see if it helps.

  Any help would be greatly appreciated?

  HI Maria/Winston.Not, trying to be coy but. I've never had close the firewall to load anything. It will be, or at least should invite you to make a choice to leave the program to run or not? Nevertheless.If you have windows activation hurt you firewall can reactivate manually without going through the bugs that you can not. If you click Start and choose the runtime application. Type cmd, and then press ENTER. When the command prompt box appears type "netsh winsock reset" without the quotes. He'll say firewall reactivated and ask for a reboot. Restart the computer and it will be active again. Just trying to help.

  Hi Winston/Hewlit,

  Thank you both for your advice.
  While waiting for your answers, I pushed all sorts of buttons and downloaded all kinds of programs in the hope that I could break the firewall (Hewlit the printer I tried to install says to disable the firewall to install the printer, and then turn it back on?).
  After a reboot, the message 'corrupt windows\system32 etc' file came and asked me to put in the original disc of Windows XP, I did not.
  Cut a long story short, I have now booked for a technician to come out as I'm totally lost.
  Thanks again for your help,
  M

• "Due to an unidentified problem Windows cannot display Windows Firewall settings" on Windows XP

  Operating system: XP w/SP3. MS Security Essentials installed.  Problem: Cannot enable or disable the Windows Firewall; When you try to do, following statement appears; "Due to an unidentified problem Windows cannot display Windows Firewall settings.l

  I've seen this before when I try to make appear the firewall configuration panel before that my computer has started completely.  Wait a few minutes and try again has always worked for me...   But in this sense, it is possible that a piece of the network process which depends on the firewall is not started on your system.  Try to examine your system and Application logs:
  (Start-> Run-> "eventvwr.msc") or
  Start-> programs-> administration-> event viewer tools
  and look for errors in the process that may not have begun.
