Fatal System Error C000021A during restore

  hansa 16:38 05 Nov 05

During windows restore get the blue screen with
'Stop: C000021A (Fatal System Error)
The Windows logon process system process terminated unextectedly with a status of )XC0000000% (0X00000000, 0X00000000) The system has been shut down.'

After soft boot system starts normally but still cannot restore.

Using XP with SP2.

Restore was to get back to before installation of Picasa.

Any help much appreciated. Will be in an out over the next day or two so may not be able to acknowledge immediately. - Thanks

Thanks VoG™

I'm afraid that this level of information is way beyond me. However, maybe this explains more. can't remember what happened at this time

'From Dr Watson':
Application exception occurred:
App: C:\WINDOWS\PCHEALTH\HELPCTR\Binaries\helpctr.exe (pid=2844)
When: 01/11/2005 @ 19:53:15.078
Exception number: c0000005 (access violation)

Not sure that I will be able to create a dump file or I am getting too far ahead?

Managed to restore to condition before 1st Nov which was a software distribution service 2 and subsequent restore. Can't remember what was updated, but it messed up the fast user switch.

Thanks again VoG™ for giving me some ideas.
