LSASS.Exe Error !!!!

Hi there...does anyone know how to resolve this error.??

Everytime the system boots up, the message will prompt "LSASS.Exe Error" -
"Endpoint Format is Invalid" , after u acknowledge it by taking "ok" the
system automatically reboots itself and the whole thing just repeats itself.

I have tried re-installing XP, repairing XP , removing and creating new disk
partitions to install OS, tried disconnecting existing hard drives and
install XP on a new hard disk also doesn't work. I keep getting the above
message every damn time.....I can't boot up to recovery console also as it
prompts for an "Administrator" id which i dunno came from where... I AM the
administrator!! I have already renamed the existing administrator id to my
name previously. When i tried using my password, it is always incorrect....

Is is such a waste to throw away my cpu....it's actually quite good. Dell P4
1.8Ghz.
It's apparent that the problem is not a hard disk issue....could it be that
i need to change my whole motherboard...what could the problem be? Does
anyone know? I checked on the net and some ppl actually said that it is a
driver/pagefile problem...anyone knows about this?

Problem now is that i am unable to boot up to XP, so i cannot run REGEDIT or
anything to chage the values....what should i do??

Damn i really need some help here......

You must get into the recovery console.

I had the same problem last week but with XP. Like you, I couldn't get
into the recovery console due to administrator password problems. I knew
the password, but the SAM file was corrupted apparently (this was XP).

I used one of the Linux tools to get around the Administrator password.
At some point one of the tools gave the option to ignore the password
for recovery boot. I first tried to recover the password thinking that I
had changed it, then tried resetting it to something else, then tried
eliminating it entirely, but none of those worked. I can't even remember
which tool got me around it, but the next time I booted from floppies
the recovery console didn't even ask for a password.

See: "http://home.eunet.no/pnordahl/ntpasswd/"
Also see: "http://www.petri.co.il/forgot_administrator_password.htm"
Also see:
"http://www.windowsecurity.com/white..._to_get_administrator_rights_on_computer.html"

The procedure I used, once I got past the administrator password, is
detailed at "http://nordicgroup.us/xprecovery/recoveryxp.pdf"

Also check "http://support.microsoft.com/kb/830570"

You might be able to put the problem drive onto another system with the
same file system, then put the repair configuration files into the
proper directory.
 
ITFreak,

It is very hard to see what is going on for you, particularly as
you indicate that you have removed/recreated the partition and
installed XP afresh, and yet the problem remains. This makes
me wonder whether your XP source from which you have done
this install is valid, unless the one shot below applies.

Basically, you can think of lsass as the most deep process that
is running on the system above the kernel. The message you
mention is saying that lsass is running out of system page table
space. If lsass has problems then pretty much everything else
is not going to work, so usually the system elects to shut down.

The following KB, not for XP nor a vanilla system that is not
forcing lsass to have extra code run in its process context, may
however still have some relevant info. It also seems to show
that when the "end point format invalid" is the error one may
be able to boot the system in safe mode, which would minimize
what is loaded hence (perhaps) allowing boot.

First, see if you can get at the boot.ini file to see whether for
some reason the /3GB or /PAE switches are being used.
If nothing else you might create a boot floppy set (which will
have the boot.ini to be used), if that is you have a floppy drive
on that system. I would think that you should not need to do
the reg edit mentioned in the KB, as an XP should not need
that (it might indicate that something "unknown" is tied into
the lsass process - again though, how could this be so in a
fresh install from genuine source?).
