My computer suddenly won't boot. I'm getting:
"lsass.exe - Application Error". "The application failed to initialize properly (C0xc00000005). Click ok to terminate the application". Of course all I get is a black screen with mouse pointer. Tried to boot into safe mode with same result. Is something corrupted or could it be the sasser worm.

Please help. Thanks.

Did you try "Last known good configuration"?

Did you try "Last known good configuration"?

[lewism]

Yes, I tried "Last known good configuration". Still can't boot computer.

If you have Windows CD...(if you don't have Windows CD, scroll down)

1. Insert your Windows XP CD into your CD and assure that your CD-ROM drive is capable of booting the CD.
2. Once you have booted from CD, do NOT select the option that states: Press F2 to initiate the Automated System Recovery (ASR) tool.
You’re going to proceed until you see the following screen, at which point you will press the “R” key to enter the recovery console:



3. After you have selected the appropriate option from step two, you will be prompted to select a valid Windows installation (typically number “1″).
Select the installation number, and hit Enter.
If there is an administrator password for the administrator account, enter it and hit Enter (if asked for the password, and you don't know it, you're out of luck).
You will be greeted with this screen, which indicates a recovery console at the ready:



4. There are eight commands you must enter in sequence to repair your problem..
NOTE. Make sure, you press Enter after each command. Make sure, all commands are exact, including "spaces".
These commands are as follows:

CD..
ATTRIB -H C:\boot.ini
ATTRIB -S C:\boot.ini
ATTRIB -R C:\boot.ini
del boot.ini
BOOTCFG /Rebuild

Note about the above command.
BOOTCFG /REBUILD command which searches for pre-existing installations of Windows XP and rebuilds sundry essential components of the Windows operating system, recompiles the BOOT.INI file and corrects a litany of common Windows errors.
It is very important that you do one or both of the following two things:
A.) Every Windows XP owner must use /FASTDETECT as OS Load Option when the rebuild process is finalizing.
B.) If you are the owner of a CPU featuring Intel’s XD or AMD’s NX buffer overflow protection, you must also use /NOEXECUTE=OPTIN as an OS Load Option.
For the Enter Load Identifier portion of this command, you should enter the name of the operating system you have installed.
If, for example, you are using Windows XP Home, you could type Microsoft Windows XP Home Edition for the identifier (it's not crucial, however what the name is, as long, as it's meaningful).
Here is your computer screen:



5. Following command verifies the integrity of the hard drive containing the Windows XP installation. While this step is not an essential function in our process, it’s still good to be sure that the drive is physically capable of running windows, in that it contains no bad sectors or other corruptions that might be the culprit:

CHKDSK /R

6. This last command writes a new boot sector to the hard drive and cleans up all the loose ends we created by rebuilding the BOOT.INI file and the system files. When the Windows Recovery Console asks you if you are Sure you want to write a new bootsector to the partition C: ? just hit “Y”, then Enter to confirm your decision:

FIXBOOT

7. It’s time to reboot your PC by typing
EXIT
and pressing Enter.

With any luck, your PC will boot successfully into Windows XP as if your various DLL, Hive, EXE and NTLDR errors never existed.



If you don't have Windows CD...
Download Windows Recovery Console: http://www.thecomput...om/files/rc.iso
Download, and install free Imgburn: http://www.imgburn.c...hp?act=download
Using Imgburn, burn rc.iso to a CD.
Boot to the CD...let it finish loading.
When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
Then, follow instructions from Step #3 above.

Before I try this, I'm not sure about:

B.) If you are the owner of a CPU featuring Intel’s XD or AMD’s NX buffer overflow protection, you must also use /NOEXECUTE=OPTIN as an OS Load Option. It is an AMD at least 5 yrs old.

I'll bring it into work tomorrow where there are far smarter people than I who can look at it.

...and will this preserve my original settings, programs,files, etc.

Thanks!!!

B.) applies to most of todays computers.

[lewism]

Ok, I finally backed up all my files externally. Tried the above procedure and still getting lsass.exe - Application Error. The application failed to initialize properly.

What next?

Appreciate your help...

[Broni]

Try repair: http://www.geekstogo...ws-XP-t138.html

[lewism]

Now getting "lsass.exe not enough quota". Computer is cycling thru Win XP splash screen, "setup is being restarted", the error message and then reboots.

Still wondering about sasser worm. What next?

[Broni]

That would be the case, if the file was isass.exe

[lewism]

Did a hard shut down and restart, looping from windows xp startup sceen, to "setup is being restarted", to black screen w/curser, to computer reboot. Don't see the error message any longer however.

[Broni]

Is this after running repair install?

[lewism]

Yes, after running repair. Strangly enough, when I now do a hard shut down, I don't have to press the power button for 7-8 seconds, but it instantanously shuts down...

[Broni]

Is this laptop or desktop?

[lewism]

Desktop...
