HELP : laptop boot issue (lsass.exe 0xc0000008 error)

[harris1986]

Ok guys my mum and dad's laptop has gone screwy and everytime i boot it up i get to the logon screen and receive a error message:

lsass.exe - System Error
Security Accounts Manager initialization failed because of the following error: The handle is invalid, Error Status: 0xc0000008. Please click OK to shutdown this system and reboot into Safe Mode, check the event log for more detailed information.

i have read that i need to do a os repair for my laptop using the laptop os disk! after inserting the disk i try to click repair and it asks for a administrator password? i have no idea what this is and it hasn't been changed from default but i don't know what the default pass is, does anyone know?

if anyone could help with either the problem, or let me know what the default admin password is would be really really helpfull

yeah tried that to no avail , it wouldn't be too bad if i could get into my desktop but i can't get there due to the problem so i can't even create a new password!

Is the machine up to date regarding OS patches?
boot into safe mode - without network. whilst in safe mode remove or disable network cards. Reboot system and if you can get in, scan for virii / trojans. This error CAN occur because of worm infection trying to exploit lsass.

it has 3, it's lsass.exe and kitten i can't get into desktop this is the problem, as the error screen comes up before i get to log on and no matter what mode i boot in i can't bypass it, think it's going to have to be a reformatt which sux lol
