I was hoping someone could give me ANY direction to resolving this issue. I am getting the lsass.exe system error, password not valid. Here is what has transpired:
I have a Dell Laptop (Latitude). It performed an automated Windows update overnight and rebooted. When I got up the next morning, there was a black screen saying the system32/system file was missing or corrupt. After reading posts on this and other forums, I ran chkdsk /r twice and then replaced the registry file (system) - by going back to an earlier system restore point. After doing this, I rebooted. After doing this, it started to boot as normal, but came to an error (lsass.exe) stating that my administrative password was incorrect. I have never created an administrative password. I attempted to go into the Recovery Console (using the original Dell Installation CD that I have) and could not get past the prompt where I am asked for the administrative password. (I tried just hitting enter, it says invalid password.) After 3 attempts, the system reboots. I have attempted to log in as last good config, safe mode...nothing works. I also just attempted to select Set Up Windows XP and then Repair, instead of going into R for Repair Console as I had been doing. It did go through the repair process, but after rebooting, the same lsass.exe error appeared. At this point, I have no way to access Windows & no way to access the Recovery Console, so I do not know how to perform any type of repair solution that is offered under any of these threads. My computer is just in a perpetual rebooting sequence...boot, lsass.exe error, reboot & repeat. Any assistance would be greatly appreciated.
