<ake sure you update windows windows up-to-date from http://windowsupdate.microsoft.com

You will need access to another system (other than the affected system) that has Internet access and six blank/formatted 3.5 inch floppy diskettes.  


Log on to the Internet (on the second system), and navigate to the following Microsoft site:

http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=E8FE6868-6E4F-471C-


Download the file to the desktop on the second system, and then double-click the icon for the file.
It is a self-extracting diskette creator and will prompt for each of the six diskettes.

Once the diskettes are created, take them back to affected system, and insert Diskette 1 into the floppy drive.

Power the affected system on.

After booting to the first of the six diskettes, insert the Windows XP CD in the CD drive.

Insert and eject each of the remaining diskettes as the computer prompts.
After the sixth diskette loads, a prompt for the Type of XP setup appears.

Press the <R> key to select Recovery Console.
A prompt for the Windows installation you want to repair appears.

Press the <1> key, then press the <Enter> key.
A password prompt appears.

Press the <Enter> key.
A C:\windows\> prompt appears.

Change the directory to the C:\windows\system32\dllcache folder by typing the following command at the C:\windows prompt:
cd \windows\system32\dllcache
(Ensure you press the <Spacebar> key between cd and \.)

Press the <Enter> key.

Copy the LSASS.EXE file to C:\windows\system32 by typing the following command at the C:\windows\system32\dllcache> prompt:
copy LSASS.EXE C:\windows\system32\LSASS.EXE

Press the <Enter> key.

Remove the diskette and CD from system.

Type the following text:
Exit

Press the <Enter> key.
The system will reboot.

Thanks...

The above link is invalid, do you have an accurate one?

You really should just open another thread and ask, but since I was still subscribed to this thread, here is a good link to MS boot disks...
