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.

Sometimes RAM memory cannot be slotted properly or just purely switching them in slots can solve the issue. Take RAM out, clean memory slots, clean motherboard connectors for them, and place them back in a different order. If by any chance none of the methods worked, then the issue might be in the hardware itself, either memory banks themselves, motherboard, power supply, etc. If this is sadly the case, you will have to locate the issue and replace the faulty part. If you are not technical enough for this adventure, the best solution is to take a PC to a computer repair shop.

  • From there, look for the following services:
    • Windows Update – Manual (Triggered)
    • Background Intelligent Transfer Service – Manual
  • Now open their Properties and make sure that their Startup type is as mentioned above and that they are running. If they are not running, just click on the Start button.

Option 2 – Run the System File Checker Scan

If the registry tweak didn’t work, you can run a System File Checker scan instead. It is a built-in command-line utility that replaces bad and corrupted system files to good system files that might be the cause why you’re getting the error when you try updating your computer. To run the SFC command, follow the steps given below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Restart your computer.

Option 3 – Run the Windows Update Troubleshooter

If the System File Checker wasn’t able to resolve the Windows Update error, you could also try running the Windows Update Troubleshooter as it could also help in fixing any issues related to Windows Update including this one. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Try to disable your antivirus program

Disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 5 – Try deleting the files from the SoftwareDistribution folder and resetting the Catroot2 folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.
  • Open the WinX Menu.
  • From there, open Command Prompt as admin.
  • Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauserv net start cryptSvc net start bits net start msiserver
  • After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
  • Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:
  • Type each one of the following commands.
net start wuauserv net start cryptSvc net start bits net start msiserver
  • After that, exit Command Prompt and restart your computer.
