This is a fresh install of Windows XP Pro SP2.  I run all other updates including driver updates from Windows Update site.  The last thing I installed is the SP3 update and I end up with BSOD and this error:

STOP: 0xC000021A {Fatal System Error}
The session manager initialization system process terminated unexpectedly with a status of 0xc000026c

Hi there;

Hotfix number 890859 is the culprit..Check for it...
Use this link:

Create boot dics (6) for XP Proff
Make your pc boot thru floppy dirve
Choose R to repair
choose 1
enter admin password

chdir $NtUninstallKB890859$\spuninst
BATCH spuninst.txt
(It copies back some deleted files.)
Type exit
and restart and enter in Safe Mode.
goto Start>Programs>Acessories>system tools>system Restore

Choose a date before you installed the microsoft updates
follow the steps.
It fixes your pc.

Best regards...

Sorry folks but I already tried the two links Igor left me and jazzIIIlove, that update isn't on my system.  

As I stated in the description, this was a new install of Windows XP Pro with the SP2 already loaded.  The relativally few updates installed prior to the SP3 update all start with KB9xxxxx.  No other software has been installed other than the OS and the updates mentioned.  

I had rebooted the system several times prior to and emediatellly before installing the SP3 update with no problems on the start-up.  The BSOD only occurred after the SP3 Update.  I've had one other system fail after the SP3 update, but it would at least boot into safe-mode and I was able to use system restore to get out of it.  No such luck on this.  

I'm hoping to sort this out without going through a Re-install of everything because I don't want to take the time to do that and run into the same problem.  Thanks for the feed back and if anyone else has an idea, I'm all ears....

So safe mode doesn't work either?

I appreciate the time you folks have given on this matter.

Out of all the suggestions I have seen thus far, most concern conditions that don't pertain to my settup.  This is not an HP or Compaq computer, it doesn't have an AMD cpu but is an Intel, and has an intel Chipset as well.  The Windows install is one of the system builder's copies of XP, and the update that seem's to be causing most of the fuss, isn't on and was never installed on the system to start with.  

As much as I would like to keep hacking at this, I am forced to go ahead and reinstall the system and I will attempt to install the SP3 update from the ISO version I've since downloaded from MS.  Odd that they have three different versions of the install package that range from 175M to over 500M in size.  That's quite a discrepency and it makes me wonder what was left out of the 'Microsoft Update' version I first installed that caused all the problems.

If after I install the OS and use the ISO version of the update, I still have problems, I'll just shoot the computer....  If I don't have any more problems, I'll be back to report that as well.
Thanks again for the help.

After my reinstallation of Windows, I followed the update procedure I used previouslly with the exception of using the ISO version of the SP3 Update.  This went through fine and all subsiquent updates have installed without further problems.

I'm inclined to believe that there may be something left out of the Windows Update version of the SP3 as it said the size on download was only 178M.  

I do Have an HP computer that has already given me a BSOD after the SP3 update, but I was able to get that system to boot into safe mode and used System Restore to Undo the Update and got the system up and running again.  I'll try to use the ISO version to do the Update and see if I can avoid the BSOD.  If this works I'll post it to one of the other Situations concerning the HP problems.

Thanks again for the input, I wish we could have come up with a way to recover this with out an OS reinstall.
