I fix PCs for a living. My customer (running Windows XP Home SP2) just sent me this:
"I deleted some entries from my registry using regedit ....The entries were in folders named "LSA".
Now when I try to start my computer (HP Pavilion Laptop) I get the message "lsass.exe - system error: Object Name not found""
Is there any way to fix this (assuming I have a Windows XP Home SP2 CD) WITHOUT doing a repair install. As repair installs from a Retail CD (not the one that came with the PC; he can't find it) only work about half the time in my experience. Even from his CD (he is trying to find it) repair installs do not always work. Also some HP PCs come with Recovery CDs that can ONLY be used to reformat and return PC to state it was bought in; ie they can NOT be used for Repair installs.
(1) Is there a way to fix this SPECIFIC WELL DEFINED PROBLEM from the Recovery Console that one gets to by booting from the CD and typing R at the first prompt.
(2) is there some way to run sfc /scannow here. To my knowledge this command only runs after a PC fully boots to the desktop. I KNOW it will not run from the recovery console BTW.
(3) Any other way to fix this short of a repair install?
