Doesn't look good.
You can always reinstall xp to another partition and dual boot into it
then recover your stuff. - but everything points to a virus (I know
you stop'd the process) so you might want to use a LiveCD
http://www.knoppix.org/ to recover if nothing else works
Might also boot into the XP CD recovery and run FIXMBR (mention'd
below as Fdisk /mbr

"title: lsass.exe - System Error when booting Windows XP Home
asked by ewhitaker on 05/11/2004 01:16PM PDT
I just built an AMD Athlon XP system with an Asus A7V8X-MX SE mother
board, an 80GB drive and 512 DDR. Windows XP Home installed but I get
the following error each time the computer boots."
I'm posting the reply as it's a pay site.

Have you run HD diagnostics yet? Memory diag?:

Are you connected to the internet? If so try disconnecting from the
internet and installing.

Are you doing all this connected to the network?
It could be a worm or virus propagating in the network, try working
disconnected from the network, then repartition/reformat/resinstall to
see if it stops.
If it repeats and you're not networked then it MUST be a hardware
error. As simple as a BIOS setting or as complicated as a faulty MB,
and anything in between.

If the above does not resolve it how are you partioning with a 3rd
party tool or fdisk ?
If you were having previous problems with the O.S. wiped the drive and
then tried a reload and it is still giving a problem it may be
possible the MBR is causing part of the problem if you have no choice
but a reload, reload it unconnected to a network fdisk /MBR the drive
do this command several times and then format the drive as fat32 or
what not using a standard windows 98se bootdisk which is available
here

Well, Memtest86 gave me the thumbs up. I did the fdisk /mbr, deleted
the partition, created a new one and currently am in the process of
formating the new partition in NTFS. The system is unpluged from the
network. Before I put it back on the network I think I will load the
security update briancassin listed above and maybe ZoneAlarm too.
I'll let you guys know in an hour or so if this works.

That seemed to do the trick. At first the last part of the windows
setup keeping appearing again after each reboot but after a windows
update it stoped. All is right with the world again. Thanks for all
of your help.
