Windows xp error c000021a

When I connect my laptop I have a system fatal error c000021a

computer does not start!

Help, please

Hello

The STOP 0xC000021A error occurs when Winlogon.exe or Csrss.exe. When the Windows NT kernel detects that or the other of these processes has stopped, it shuts down the system and triggers the STOP 0xC000021A error. This error may have several causes. Among them are the following:

·        Incompatible system files have been installed.

·        A Service Pack installation has failed.

·        A backup program used to restore a hard drive does not correctly restore files that may have been in use.

·        An incompatible third-party program has been installed.

I suggest you to follow the steps mentioned in the article below and let us know your progress.

  • Windows update error 80072EFD

    Hello
    I have a laptop of old P750 for 2 months, after they need to do a restore to a disk upward, I now get the above error.
    I then decided to do a cover of toshiba with a clean install and still get the same result of windows update is not not able to connect to the server.

    I tried everything I can find this error, including the verification of the proxy settings for WU, reset the proxy via CMD prompt settings.

    I noticed something interesting while control validation using microsoft MGA diagnostic tool, where windows has been listed as a hat, but note some reports as:

    Validation code: 0
    LegitCheckControl: N/a, hr = 0 x 80070002
    signed: n/a, hr = 0 x 80070002

    My understanding is the way to 0 x 80070002 he couldn't connect identical to WU or that files are missing.

    I have rebuilt that recommended such c:\Windows\SoftwareDistribution records, turned off all firewall, removed antivirus / software malware but still no luck.

    It seems funny how the same thing happens even after a clean drive toshiba recovery.

    Any suggestions?

  • Windows Update error code

    I have a new Toshiba laptop, running Windows 7 (Home Premium SP1 installed by the OEM). My internet connection works fine for all sites Web except it fails when I try Windows Update. Error message code is 8024402F. I already checked 'automatically detect DNS settings' I also tried disabling my firewall (McAfee) temporarily and tried without solution. I tried dozens of times in recent days.

    Any suggestions on how to fix this?

    Hello

    According to the Microsoft Knowledge Base, it has something to do with your Internet connection. Have you already checked the Microsoft Knowledge Base?

    Microsoft recommends disabling the security software (antivirus and firewall) and try the troubleshooting Windows Update tool as described here:

    First you get a Toshiba Recovery CD and not an original Windows OS CD.
    In this case, if you want you can retrieve the whole OS. All Toshiba drivers are preinstalled on the image.

    Now to the error:
    cfsserv.exe is a process belonging to Toshiba ConfigFree utility and search wireless devices.
    However, malware often use the names of valid program to try to hide themselves. So, please run a full scan with Ad-Aware in making sure you have the latest definitions file.

    If it doesn t work I recommend the ConfigFree tool for some audit settings.

  • Connection Manager HP stopped responding + Windows Installer Error 1719

    I am running Windows 7 (SP1) 64-bit operating systems.

    Started getting an error message of connection manager HP "HP Connection Manager Service has stopped responding.  Error code 8008005.

    HP Connection Manager v4.1.23.1 running.
    When I try to install a new version of v4.4.10.1 (SP58930) HP connection manager, I get an error of Windows Installer 1719.  Tried different solutions recommended for this, but nothing has worked.

    I see in the forum after this uninstall of the current version and then install the new version of the HP connection manager can solve my original problem.

    Before uninstalling the currenet HP Connection Manager version, I wanted to be sure that I will be able to install the new version without encountering Error 1719.  I don't want to be in an even worse situation of not being able to the HP Connection Manager after you uninstall it.

    Can I get confirmation from HP that I will be able to successfully install a new version after uninstalling the current version?

    A ran the Microsoft Fixit then tried to install it and got the Windows Installer Error 1719.

    Then uninstalled HP connection Manager.

    Tried to install the HP (SP58930) connection manager and still have the error Windows Installer 1719.

    What do you suggest I try next?

    The fact that HP Connection Manager is no longer installed, how this will affect my computer?

    The fact that it is no longer installed will have no effect on the functioning of your laptop and none on the operating system.

    HP connection manager is simply a utility assistance for people who are making it difficult for the network through conections wifi and bluetooth connections.

    If you are not in this group it is really useless.

    From your description, it seems that if you can't follow instructions in the Microsoft fixit to the letter. By using the fixit is the easiest way to remove the registry entries and make changes to the registry that will allow installing and uninstalling software.  I can't recommend the methods that I use personally when I run on these issues because they involve access to the registry via regedit. The word people have never even heard of Regedit. Using Regedit can be a very bad thing for someone not experienced in the use of the registry editor.  All ch = angels did take place immediately and which included all the mistakes made during the access to the registry. Ongoing work on an operating system can fairly easily through the registry editor. Try the Microsoft fixit. It is a safe utility. Use it after an attempt to install and leave the window open until after error that does compete with the installation of the software.

  • I have a black and white 2 on windows installation error 7...

    I have a black and white 2 on windows installation error 7...

    things are running smoothly for me until the last part... that says "black and white 2 cannot install. your system has not changed. Re-run the installer to try again. "Error: the filename, directory name or volume label syntax is incorrect"

    guys what should I do... Please help me... I like this game very much

    I tried to disabled my firewall and antivirus to install this game... OO with regard to the compatible thinggy that I n tried yet coz I can't even install the game in my lappy windows7...


    guys what should I do... pls help >< i="" love="" this="" game="" so="">

    If it isn't your game, then the Compatibility Center W7 says that is not compatibile. But it seems there are other versions that can run.

    Make sure that your installation discs (if his coming to a CD/DVD) are all the scratches/dirt free and clean. A bad scratch or dirty mark on a disc can cause 'odd questions' sometimes.

    There are a few things to try:

    1. find the Setup program you are running for the game and which run in XP compatibility mode.

    2 in case of failure too and then try to run it in XP Compat mode and as administrator.

    I noticed there are a few paths on the www, if you get it installed, it may be an idea to get patches and install them to the best game(check AV before installing).

     

  • Windows Update, error 80200010 # WindowsUpdate_dt000

    The message referenced above is the error in trying to fill three 3 important updates to my computer, I received.  Two 2 updates installed correctly and completely, however, one (1) does not.  In chicking on icon troubleshooting he, I will put this error message "WindowsUpdate_80200010" "WindowsUpdate_dt000"  What does this mean and how can I fix this error and get this update loaded on my computer.

    http://Windows.Microsoft.com/en-us/Windows-Vista/Windows-Update-error-80200010

    If Windows Update error 80200010 during updates, this means that the Background Intelligent Transfer Service (BITS), cannot access the Internet. This service is used to connect to the Windows website and download updates to your computer.

    To fix this problem, make sure that your computer is connected to the Internet and check for updates again. To easily see if you are connected to the Internet, point to the network icon in the notification area and wait until you can see the status of your connection. You will see the name of your network or the service to which you are connected and the type of connection you have. If you are on a company or home network, you should see the message access: Local and Internet.

    I figured Vista in this case.

  • Windows system error: there is an IP address conflict with another system with the network. How do I remove this error message?

    I just installed a new internet provider and all of my connections are working fine, but I constantly get this "Windows system error: there is an IP address conflict with another system with the network." I have my electrician of the internet modem connected to my office. I have also two wireless devices connected to the appearance of the Modem wireless. I constantly get this error message mentioned above, and I want to get rid of it.

    This means that all that he says.  Your Windows system has an address that already exists on your local network.  Turn your system off and use a working system to locate this address and to which unit he belongs.  In most LANs, the router's DHCP server.  You may be able to ask the router which addresses are used and see what device uses this address, but I suspect not.

    Duplicate addresses can occur when two systems received the same address manually, or when we got an address in the DHCP of the router range. It is unclear when this happened because he is not in control of the address and puts the address duplicate to a second system.  You need to track down, ensuring that all addresses manually asigned are out of the DHCP range, that you book the address of the router, if you want the device to use this address, or configure all devices to request the address of the router using DHCP.
