Re: Stop 0xc000021a error

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I do have access to a 2nd PC, but I was hoping that there was a way to avoid
a reformat/restore. I would think that there has to be a way to find the
offending file/driver/service.....

Background information on Stop Error code:
http://msdn2.microsoft.com/en-us/library/ms797159.aspx

This occurs when Windows switches into kernel mode and a user-mode
subsystem, such as Winlogon or the Client Server Runtime Subsystem
(CSRSS), is compromised. Security can no longer be guaranteed. Because
Win XP can't run without Winlogon or CSRSS, this is one of the few
situations where the failure of a user-mode service can cause the system
to stop responding. This Stop message also can occur as a result of
malware infestation or when the computer is restarted after a system
administrator has modified permissions so that the SYSTEM account no
longer has adequate permissions to access system files and folders.

Do you have data you wish to recover. Do you have acces to a second
computer preferably a desktop? Putting the problematic drive in the
second computer as a slave may be the best way to backup your data. You
can then use the recovery partition to restore the PC to factory
condition.

Hope this helps.

I have a Windows XP Media Center PC that is giving me a STOP:
0xc000021a error every time I try to boot it up, either in Safe or
Normal Mode. The error says "The Windows Logon Process system
process terminated unexpectedly with a status of 0xc0000020
(0x00000000 0x00000000). I have tried booting using Last Known Good
Configuration, but that does not help. Norton Partition Magic I
believe caused this error, as I was trying to move some free space
from one partition to another on my PC. I can access the data on the
drive, but it just will not boot. I have looked at
http://support.microsoft.com/default.aspx?scid=kb;en-us;156669 but I
am not sure that will help me, as I cannot boot the PC, therefore I
cannot set Dr. Watson as the default debugger or use the userdump.exe
tool either. Any ideas as to what I can do to figure out how to fix
this? The PC is a Sony Vaio that did not come with recovery disks,
just a recovery partition that will restore the PC to factory
condition, which I really do not want to do if I can help it. From
what I am reading, it appears to be a problem with the winlogon.exe
failing, but I am not sure how I can fix this. Any ideas would be
appreciated. Thanks for any help.
