Reason
Error 0xC000021A occurs when Winlogon.exe or Csrss.exe fails. When the Windows NT kernel detects that each of these processes has terminated, it crashes the system and returns a STOP 0xC000021A error. This error can have several problems.ichin, including:
- Incompatible system files installed.
- Failed to install service pack.
- A backup program commonly used to restore a hard drive could successfully * restore files that were not yet available.
- An incompatible third-party program is currently installed.
Resolution
To solve this problem, you need to understand which of these processes failed and why.
To determine which process has failed, Dr. Watson for Windows NT writes diagnostic information about process A errors to the Drwtsn32.log file. You can also configure this program to dump files with invalid descriptors. You can then analyze the files with a debugger to understand why the summary is not being executed.
In Dr. To configure Watson to detect custom mode errors, follow these steps:
-

In this single prompt, enter System Root System32 Drwtsn32.exe and -i’ve then press Enter.
This command configures Dr. Watson as a systemdefault debugger.
-
When prompted, enter System Root System32 Drwtsn32.exe and then follow these steps:
- Add to existing signature file
- Create crash dump
- Visual notification
-
Start Dr. Watson (Drwtsn32.exe) after a hard restart after a STOP 0xC000021A error.
-
See Dr. Watson log to determine which process in user mode might be causing the problem.

If Dr. If Watson did not create a custom User.dmp file for Winlogon.exe or Csrss.exe, you may need to use various tools to clean up memory associated with the file where the process crashed. For more information, see the following article:

Note
How do you check for syntax errors?
Make sure you and your family are not using a Python search term for a variable name.Make sure you can have a colon at the beginning of every compound statement, including for, while, if, and def statements.Check if the indent is long.Make sure all lines of code have matching quotes.
Follow the instructions in the Knowledge Base article to troubleshoot the process asIt will stop with one exception. While following these monitor instructions, do the following to resolve STOP error 0xC000021A:
- Winlogon.exe
- Csrss.STOP exe
Most 0xC000021A errors occur due to Winlogon.exe crashing. This is usually due to an imprecise third party Graphical Authentication and Authentication (GINA) DLL. GINA is a replaceable component DLL that Winlogon.exe appears to be loading. This implements the interactive connection model validation policy. GINA performs all actions to identify and authorize users.
Some types related to remote program control very often replace the standard Windows GINA DLL (Msgina.dll). The first step is to check the system for the presence of the third party GINA DLL. To do this, find the required registry key:
- If the Gina-DLL value is present and looks more like something other than Msgina.dll, it probably means that the value was changed in the correct third-party product.
- If this problem does not exist, the system will use Msgina.dll and the GINA DLL will be used by default. If the error is in the stat If it first appeared after installing a new or updated device driver, system help, or third-party software, the new software will actually be removed or disabled. Check with your software type to see if an update is available for Fantastic.
