lsass.exe - System Error

XP Home installed machine, AMD 1.8 processor, 80 GB HD, 512 MB mem - Had a lootseek infection in Thunderbird that I finally removed and then I could not boot in any mode. Machine would recycle. I could briefly see (flash) a bsod with writing before recycle.

Did a repair install and now I can get to the blue installation screen and installation freezes with an error message box: lsass.exe - System Erroe; An invalid parameter was passed to a service or function.

Any assistance would be appreciated.

 

Thank you for the reply and suggestion.

Yep, did that and thats when it stopped booting and started cycling. At that point I decided it was time for a repair try, and thats when I got the lsass.exe error.

 

Yes, everything I found said the (i) and (L) were the ones to check. lsaaa.exe is where it should be and dated correctly.

I took the hard drive and slaved it in another machine and scaned it with everything I had before I tried a repair. Sure don't want to format and reinstall everything, but I'm about out of ideas. Thats why I posted here, hoping, hoping, hoping.........

 

Like I said......I didn't want to do that. I will wait a few days since I don't have the time now as I'm off to run some errands and I work the next two days. Maybe someone will read the post and be able to suggest a fix other than copy and reformating. Thanks for the help.

 

I have this same problem. Should I start my own thread?
Can you boot into XP at all arky41? I can't whatsoever, not even safemode.
Mine was saying the same thing as yours for awhile...

"Isass.exe -System Error
An Invalid parameter was passed to a service or function".

Then a few weeks or a month later when I tried again it said this:
"Isass.exe-System Error
When Trying to update a password, this return status indicates that the value provided as the current password is not correct."

If anyone could help me, I'd greatly appreciate it.

 

Sorry it took so long to get back to you.

I could not find a way to fix it so I moved the hard drive to another PC as a secondary and copied all my needed files, then did a format and reinstalled my OS and have slowly been adding programs back.

I believe that you can also install a second copy of the OS or at least create another partition and install the OS on it.

Best of luck.

 

It's quite alright.

Well..the problem occured on a laptop, would that make a difference?
I should remove my hard drive and attempt to retrieve data then format?
Is there a difference between reformatting and format?

How would you install a second copy of the OS?
What is a partition and how would you create one?

I would like to point out that I'm computer illiterate. I'm sure you've noticed that already.
