comment Home > Computing > Windows > System Performance Fixing Stop Error C000021a in Windows written by: Donna Buenaventura•edited by: Bill Fulks•updated: 2/9/2011Are you receiving a stop c000021a fatal system error message when using Windows? Do you want to fix a c000021a error code without sending the computer to a local tech shop? Just follow these steps. slide 1 of 4 What Does Stop 0xC000021a Error Code Mean? The Windows 0xC000021a stop error code occurs when critical system processes fails to run, like when the Winlogon.exe and Csrss.exe processes have stopped working. The Windows NT kernel will detect it and raised the stop C000021a fatal system error message or bluescreen (BSOD). It occurs because of a faulty third-party Graphical Identification and Authentication (GINA) DLL which is a replaceable DLL component that Winlogon.exe loads. There are several causes of bluescreens with the stop c000021a error code. Among them are the following: Mismatched system files have been installed. A Service Pack installation has failed. A backup program that is used to restore a hard disk did not correctly restore files that may have been in use. An incompatible third-party program has been installed. Malware infection. Power supply unit (PSU) needs replacement. slide 2 of 4 How to Fix Stop C000021a Error in Windows All versions of the Windows operating system use winlogon.exe and csrss.exe but if you've recently install new drivers, system services, or programs in Windows, you likely encountered the stop C000021a error message because of the said changes on the system. To try fixing C000021a error in Windows, you need to determine if there is third-party GinaDLL: Open registry editor in Windows by typing regedit.exe in the run box. Hit enter key on the keyboard. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon In the right pane, determine if there is GinaDLL REG_SZ value.
