A Quick Guide to Fixing the Stop C00002lA Fatal System Error

Stop C00002lA Fatal System Error- What is it?

C00002lA Fatal System Error is a blue screen of death error that may occur when you start your Windows NT 4.0 based computer. This error causes the screen to turn blue and the system also shuts down.

The stop C000021A error message is displayed in the following format:

Stop c000021a {Fatal System Error}
The session manager initialization system process terminated unexpectedly with a status of 0xc0000017 (0x00000000, 0x0000000) The system has been shut down.

Error Causes

The stop C000021A error occurs when either Crsrss.exe or Winlogon.exe fails. When the Windows NT kernel identifies that either of these processes has failed, it stops and the error code stop C000021A appears on the computer screen.

Here are some of the underlying causes for the stop C0000021A error:

  • The incompatible third-party program
  • Hard disk issues
  • Service pack installation has failed
  • Mismatched system files have been installed
  • Bad and invalid registry keys

Further Information and Manual Repair

To resolve the stop C000021A Fatal System Error on your PC try the following solutions:

  • Remove Incompatible Third Party Programs

If the error occurred after you recently installed a new program, then it is advisable to remove that program. The error occurs due to the incompatibility of the program.

To remove the program go to the start menu and click on the control panel. Now click on Add/Remove Program tab and double click on the program name that you recently installed and remove it from the list.

Once removed, not reboot your PC. Reinstall a compatible program and run it. It is most likely to resolve the issue. However, if the stop C000021A error still occurs, then it means the problem is critical. It is related to the registry.

  • Repair and Restore the Registry

This procedure is slightly long and tricky.

To try it, you need to be technically sound. Here’s what you have to do: first create a parallel installation of Windows NT.

Start your PC to the parallel installation and then open the Registry Editor. On the Registry Editor’s Windows menu click HKEY_LOCAL_MACHINE on Local Machine and then click Load Hive.

Now type the path %systemroot%system32configsystem into the System hive of the prior installation. Then click open. Here you will be prompted to enter the name of the key, type TEST.

Note the setting for the current DWord value in the preceding registry key. This is 0x1 and is denoted by CURRENT:Reg_Dword: 0x1.

This value indicated that the Current Control Set for your original Windows NT installation corresponds to ControlSet001 in this window. Now if the value is 2, it indicated that the Current Control Set corresponds to ControlSet002.

Now locate the following registry key:

HKEY_LOCAL_MACHINETESTControlSetXXXControlSession Manager. XXX is the Current Control Set Value. And delete any pending file rename operation entries. Then click TEST hive and then click Unload Hive. After that again repeat the process, open the registry menu and click load hive, here type the path %systemroot%system32configSoftware to the Software hive of the prior installation and then click open.

Now you type TEST 2 when you are prompted for the name of the key. Remove any pending file rename operations entries in the following registry keys:

HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnce

HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceEx

Now click TEST2 hive and then click unload hive. Quit the Registry Editor and then restart your original installation.

This will resolve the stop C000021A error.

Gigabit internet showing as 100MB in Windows
In today's world setting up a LAN network or internet connection is no longer a daunting task that will require having a bachelor's degree in computer science nor a specialized technician. But even in the present-day environment issues and problems can occur. One of these problems is detecting or running a network at a slower 100MB speed instead of 1GB. Troubleshooting of this nature is somewhat more complex than your typical troubleshooting issue because several things including hardware could be involved in this particular problem but do not worry, we are here to back you up and guide you Setting up a home or small office network no longer requires a specialist technician to constantly monitor and optimize the LAN routers and connected PCs. As Windows networking has improved and new features have become available on the hardware, configuring a 1GB network should be as simple as connecting the LAN to a router that came with this capability. If however the network’s rated speed only gives 100MB, troubleshooting the issue is more complex. To find the problem, you’ll need to check the hardware devices, cable connections, and the software you are using to connect and manage the network.

Hardware checks

If you are using the switch in your LAN configuration check its hardware details as well to see if it can handle 1GB speeds.
The next step is network cables, some cables are not designed and their copper can not transfer 1GB of flow, check to see if your cable is classified for the desired speed. To visually check cables do the following
  1. Check both connection jacks to see if it has any loose or frayed wires. If any of the wires are loose, it can be the cause of the performance issue. You should replace the cable if you discover damage to the connectors.
  2. Inspect the entire length of the cable and check if the harness shows any clear signs of damage. A bent or damaged cable can reduce the amount of information it’s capable of transferring between the PC and LAN router. If you find any damage to the cable, replace it to restore your network speed.
  3. Is the cable capable of transferring 1GB speeds? Different network cables support different network speeds. A Cat-5 cable will only provide 100MB transfers, while a Cat-5e or Cat-6 can support up to 10GB transfers. Check the cable’s labels to make sure you are using a Cat-5e or higher-rated data cable.

Now when the hardware issue is out of the way we can focus a little more on the software part.

Let's try the first easy solution, run Windows built-in troubleshooter

  1. Click the Windows button and type Control Panel. Then select the top result.
  2. If your Control Panel shows the Category View, change it to display Small Icons instead.
  3. From the list of available applications, select Network and Sharing Center.
  4. In your Network and Sharing Center, you can see the active network, set up a new network connection, troubleshoot problems, or change your adapter settings. Before making changes to your device properties, you can let Windows run a troubleshooter on your adapters to see if it can automatically fix your connection issues.
  5. Click on Troubleshoot Problems from the Change Your Network Settings section.
  6. In the Troubleshooter Application, scroll down and find the Network Adapter option.
  7. Click on Run Troubleshooter to let Windows check your network adapter’s configuration for any issues.
  8. Select the Ethernet Adapter you’re currently using from the list and click Next to proceed.
  9. Wait for the process to complete and check the results. If Windows detects any issues, it will recommend a fix. However, if the configuration of your network adapters does not have any problems, you’ll see a message that Windows couldn’t detect any problems.
  10. If there are any issues with the cable, the troubleshooter will detect the connection issue and request you replace the cable and connect it to your PC.
  11. It can occur that even after inspecting the cable and you didn’t find any visible damage on the housing or connectors, it could still be faulty. Replace the cable with a new one and rerun the troubleshooter to see if the cable is working as required.

If the troubleshooter finished and you received a Windows Couldn’t Detect Any Issues result, you’ll need to verify your adapter’s speed settings.

  1. In your Network and Sharing Center, select the Change Adapter Settings option from the left menu.
  2. On the list of adapters, choose the one you’re using and click the Right Mouse Button to open the context menu.
  3. Select Properties from the Context Menu to access your adapter’s settings.
  4. On the Ethernet Properties window, you can enable or disable different features and install additional protocols. To change the device settings, click on Configure to continue.
  5. This will open the Device Controller Properties window where you can check the status, make changes to the settings, find out information about the driver, or check historical events on the device. Select the Advanced tab to access the device settings.
  6. On the Advanced tab, locate the Speed and Duplex setting.
  7. The Auto-Negotiation option may cause network performance issues on certain Ethernet adapters and routers. The setting allows your adapter to change the speed settings according to the LAN configuration you connect to your PC. If you connect to different LAN networks regularly with different speeds, it can occur that the setting doesn’t update from 100MB to 1GB while switching.
  8. Change the Value to match the network speed of the LAN you’re connecting to your PC and use the manual speed setting.
  9. Click OK to apply the setting and test your network performance. If your adapter doesn’t have the 1GB setting available but you know the rating should go up to that speed, it could indicate that you aren’t using the right driver for the device.

If you don’t have the setting available or the device still only provides 100MB speeds after changing the Speed setting to a manual value, you may have to update the driver for the device.

  1. On the Ethernet Properties Window, once again click on Configure to access the Device Properties Window. Then select the Driver Tab to access your driver details.
  2. Select Update Driver from the available options.
  3. On the Update Driver window, select the option to let Windows Search Automatically for Updated Driver Software.
  4. Windows will connect to the internet and search for the latest drivers online. If a newer driver exists, Windows will download and install the driver for you. If you’re using the latest driver, Windows will inform you that no updated drivers are available.

Solution

Restoro box imageError Causes

Error code 0xc004f034 often occurs due to an issue with the Windows product key. This may occur when users enter an invalid product key or use one that is appropriate for use on a different version of Windows. To correct the issue, users will need to use the correct product key for their system or contact an IT professional if their device is connected to a Key Management Service (KMS).  Windows users affected by this error code may also need to check their system for viruses or missing system files since these issues can result in error codes on Windows devices.

Further Information and Manual Repair

Manual repair methods enable users to fix problems related to error codes. Though some manual repair methods require the use of Command Prompt and utility tools like the System File Checker, even non-technical Windows users can find success simply by following the instructions provided below.

However, note that some issues can be complex, thus requiring the use of an automated tool or help from a Windows repair technician. Consider these options if the manual repair methods below do not resolve error code 0xc004f034 on your Windows 8 device.

Method One: Enter Valid Windows Product Key

Microsoft currently offers several ways for customers to activate their Windows operating system, the most common of which is the product key. This 25-character code verifies that users have access to an authorized version of Windows.

You may get a valid product key from an authorized dealer, a new PC with Windows, or access a digital copy from a Windows website when you purchase your Windows operating system online. Once you have a valid product key, use it to activate Windows and resolve error code 0xc004f034 in Windows 8. Follow the steps below to access the Product Activation Wizard.

  • Step one: Click or tab Start button then select Settings
  • Step two: Tap or click PC Settings, then select Activate Windows
  • Step three: Type invalid product key

Once a valid product key is used, the Product Activation Wizard should complete the activation process.

Method Two: Run System File Checker

Another option available to Windows 8 users is System File Checker (SFC). This tool enables Windows users to scan and repair corrupted or missing system files. Follow the steps below to access SFC.

  • Step one: Go to Start and type Command Prompt or CMD.
  • Step two: Run as Administrator
  • Step three: Type sfc /scannow ensuring a space is between “sfc” and “/scannow”.

CD/DVD icon is not showing in File Explorer
In the past, CDs, DVDs, and floppy drivers used to be the primary sources of external storage for many users – that is until the USB storage devices took over. These days, a lot of devices no longer have a built-in CD or DVD writer or reader as it contributes to the thickness of the device. On the other hand, there are still various devices that still come with a built-in CD or DVD writer or reader. However, recently, users who still use CD or DVD on their devices reported a problem where the CD or DVD icon is not visible in the File Explorer as well as in “This PC” or the My Computer page. The cause of this issue is still unknown at the time of writing, but there are still some potential fixes you can try to fix it. You can try to update or roll back the device drivers or apply some tweaks in the Registry Editor. For more details, refer to the given options below.

Option 1 – Try to update or rollback device drivers

The first thing you can try to fix the missing CD or DVD icon is to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
  • Open the Devices Manager from the Win X Menu.
  • Then locate the device drivers and right-click on them to open the Properties. Note that the concerned drivers will be listed under the DVD/CD-ROM drives section as well as the IDE/ATAPI Controllers section.
  • From there, look for the following drivers:
    • ATA Channel 0.
    • ATA Channel 1.
    • Standard Dual Channel PCI IDE Controller.
  • Now, right-click on each one of the listed drivers and update them all. You could also try to roll them back to their previous versions.
Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver.

Option 2 – Try to use the Registry Editor

  • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
  • Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318}
  • After that, look for the DWORD values named “UpperFilters” and “LowerFilters”.
  • Right-click on each one of these DWORD values and select Delete.
  • Now restart your computer and see if it fixes the problem.

Option 3 – Try creating a new Registry entry

There is another option you can try in the Windows Registry to fix the missing icon of the CD/DVD. You can try adding a new entry. How? Refer to these steps:
  • Tap the Win ­+ R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
  • After that, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesatapi
  • From there, right-click on “ATAPI” and select New > Key.
  • After that, name it is “Controller0” and right-click on the sub-key and then select New > DWORD (32-bit) Value.
  • Now name it as “EnumDevice1” and double click on it and then set its value data to “1”.
  • Click OK and restart your computer to apply the changes made successfully.

How To Speed Up PC Startup
Hello and welcome to How To Speed Up PC Startup where we will explore how to make your PC boot-up system faster. When your computer gets older, you'll see a decrease in your PC's load time. This can be very annoying and frustrating, especially if you're not accustomed to exercising patience. Your computer's boot time does not need to be sluggish, even if it's old. While there are reasons why your computer is acting up and giving you the 'slow' sign, there are ways that you can optimize how fast your PC starts up at the beginning. Once you start speeding things up, you’ll never look back!

Start With your BIOS

You may need to tweak your PC’s start-up menu. Since the majority of issues encountered on your PC might not be related to the software running in the back end, you can focus on your computer's hardware. The ideal way to speed up your PC startup is to access your computer's BIOS when booting up. This can be accessed by holding the DEL key or whichever button is used to tap into your BIOS. You can change where your computer boots from. You can opt to put your hard disk right at the top which would elude searching for CDs and other storage media devices when your PC starts up.

Tweak Startup Programs

There are many programs that execute when your computer starts up. These programs normally run in the back end. Most times back-end programs are unnecessary and do not contribute to the productivity or performance of your computer when in use. Instead of allowing these programs to execute when your PC boots up, why not disable them?  By deactivating these programs, you'll be reducing the amount of CPU usage which will accelerate your PC performance. Additionally, there are some installed programs that you never use. Instead of leaving these programs to occupy needed space on your computer system, you can uninstall these to create more room on your computer. This actually increases your PC startup speed.

Put Malware on a Leash

Malware and spyware can cause problems for your start-up. A slow computer is an indication that your computer is plagued by malware. This affects your computer's boot time and whether or not it'll startup as quickly as you intend it to. If your computer gives you the 'virus alert', you need to download an antivirus program that will be able to eradicate all virus threats. Be mindful of where you download antivirus programs since many of them are viruses or have viruses attached to them. Some viruses are tough on your computer. This means that if an antivirus works for your best friend, it may not work for you. Since malware differs in functions and the havoc they cause, it's best to know what you're up against by doing research.

Clean Your Registry

You should also clean out your registry. The fewer unused registry keys you have lying around on your computer, the faster your computer will go. Getting a good registry cleaner from a clean source can help tremendously, but be careful; registry cleaners have the potential to be very dangerous so make sure you backup everything on your computer and only download registry cleaners from a reliable source. By implementing the above tips, you'll see quick improvements when using your computer.
