Hello Don,
The STOP 0xC000021A error occurs when either Winlogon.exe or Csrss.exe
fails. When the Windows NT kernel detects that either of these processes
has stopped, it stops the system and raises the STOP 0xC000021A error.
To troubleshoot this problem, you must determine which of these processes
failed and why.
To determine which process failed, register Dr. Watson as the default
system debugger (if it is not already the default debugger). Dr. Watson for
Windows NT logs diagnostic information about process failures to a log file
(Drwtsn32.log). Also, you can configure this program to produce memory dump
files of failed processes that you can analyze in a debugger to determine
why a process fails.
To set up Dr. Watson to trap user-mode program errors, follow these steps:
1. At a command prompt, type "<System Root>\System32\Drwtsn32.exe -I"
(without the quotation marks), and then press ENTER. This command
configures Dr. Watson as the default system debugger.
2. At a command prompt, type "<System Root>\System32\Drwtsn32.exe"
(without the quotation marks), and then select the following options:
"Append to existing log file"
"Create crash dump"
"Visual Notification"
3. After the computer restarts from the STOP 0xC000021A error, run Dr.
Watson (Drwtsn32.exe).
4. View the Dr. Watson log to determine what user mode process may be
causing the problem.
5. If the Dr. Watson log does not contain enough information to determine
the cause of the problem, analyze the User.dmp file to determine the cause
of the STOP 0xC000021A error.
If Dr. Watson did not create a User.dmp file for either Winlogon.exe or
Csrss.exe, you may have to use a different tool to generate a memory dump
file of the process that fails.

241215 How to Use the Userdump.exe Tool to Create a Dump File
http://support.microsoft.com/?id=241215
NOTE: Follow the instructions in the Knowledge Base article to troubleshoot
"a process that shuts down with an exception". While you follow these
instructions, monitor the following processes to troubleshoot the STOP
0xC000021A error:
- Winlogon.exe
- Csrss.exe
NOTE: Most STOP 0xC000021A errors occur because Winlogon.exe fails, which
typically occurs because of a faulty third-party Graphical Identification
and Authentication (GINA) DLL. The GINA is a replaceable DLL component that
Winlogon.exe loads. The GINA implements the authentication policy of the
interactive logon model. The GINA performs all identification and
authentication user interactions.
It is very common for certain types of remote control software to replace
the default Windows GINA DLL (Msgina.dll). Therefore, a good first step is
to examine the system to see if it has a third-party GINA DLL. To do this,
locate the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Value = GinaDLL REG_SZ
- If the Gina DLL value is present and is anything other than Msgina.dll,
this probably means that a third-party product has changed this value.
- If this value is not present, the system uses Msgina.dll as the default
GINA DLL.
