Hello Gentlemen and Ladies,
You've helped me greaty in the past so I thought I'd ask for help again.-
Windows XP home Ed SP2 ( i think)
Comp was running a little slow -( I have a Firewall and run an AV prog. as well)
I decided to run ad aware and then spybot search and destroy. I updated the definitions - it found quite a few issues. I checked the fix problems tab. It indicated that it fixed all but 1 of the issues and that if I reboot it may repair the remaining issue -or something like that.
I rebooted and get the following - lsass.exe - unable to locate component
This application failed to start because MPR.dll was not found. Re- installing this application may fix the problem.
Can anyone help me with this issue?

I'm even having trouble getting to the Repair screen in order to attempt a re-install. If anyone can offer suggestions I'd be greatful.
Thanks again
Dave

You might want to read this thread. It doesn't sound real promising

HI, Are you guys aware that the lsass.exe file can actually be a downloader, or a virus that will seek out your personal information. It can overwrite windows default file and just be a process that is registered as a virus. Do you all have good AV protection installed on your pcs?

Have you tried to do a Recovery, using Spybot?
Boot into Safe Mode.
How to start Windows in Safe Mode
Open Spybot.
Click the Recovery icon.
Put a check next to the problem you had Spybot fix, that caused your current situation.
At the top, click Recover selected items.
Spybot should restore the files.
Reboot into Normal Mode, and see if your problem has been corrected.

Thanks TG-
The issue is that I cannot boot into safe mode. I can get to the advanced menu screen and arrow to Safe mode boot. After hitting enter it boots briefly into safe mode then the black screen appears and the same error box comes up-
lsass.exe is missing ...etc. and that MPR.dll is missing.
I also downloaded the lsass and MPR.dll from work laptop and have it on a disk but have no way of installing it...
This can't be that hard or is it?
thanks
Dave

Have you tried Last Known Good Configuration, from the boot menu?

Hey TG,
Yes, unfortunately I tried that without success. What puzzles me is that I can't force it to boot from a CD. I can get to a boot menu, tell it to boot from cd but it spins up and still boots from the hard drive...

I noticed you added you posted a HJT log. Be patient, It takes awhile and all the experts there are busy. They will get to you. I would suggest you wait until you're given a clean bill of health before doing anything else

Actually, it was removed from the HJT forum. I'm placing my faith and sanity in you guys...
I couldn't even run HJT to get a logfile

OK- I'm now able to boot from CD - the XP installation disk. I also have my missing file MPR/dll on a nother CD( downloaded it from work)- so my question is when I get to the set up XP screen I can go to the "R"epair screen. But can I somehow install the MPR.dll file ai have on my CD or do I need to do the "fixboot" command?
Thanks
Dave

fixboot is a command to fix the master boot record. using the Recovery Console. If you could get into safemode you could run System File Checker

Recovery Console commands
