I too have received this message:

Security Account manager initially failed because of the following error:
The handle is invalid: Error status Oxc0000008. Please check OK to shutdown
the system and reboot into Safe Mode, check the event log for more detailed
TRied a repair but that failed, read the article at;en-us;316751

Looks to me like another rebuild, twist to the story is that this was
rebuilt last Wednesday, and today same problem, any ideas why this is
happening, I am not looking forward to rebuilding this system weekly.
