If safe-mode doesnt work,then boot pc to xp cd,at xp installation,press the  r  key

at recovery console,select 1 for C:  press enter for password.Recovery options/help

You do not describe symptoms consistent with a missing or corrupt lsass.exe file but you can sure try replacing it is you want and then you will find you have the same problem.

The real problem is more likely that your hard drive on your system of unspecified make and model has no more room on it and you are going to have to boot on something else in order to check that and free up enough space to allow your system to boot, then do some maintenance to clear some stuff off your hard drive.

The symptoms of a missing or corrupt lsass.exe file are described further down.

If you want to see if you can resolve the problem you have to provide more information:

Unfortunately, the MS Answers forums implementation does not prompt for any system information when a new question is asked, so we know absolutely nothing about your system.

Not knowing fundamental information about a problem prolongs the frustration and agony of resolving these issues but that is the way they choose to run things here.

Thank you MS Answers owners, for continuing to make the resolution of simple problems as frustrating and time consuming as possible.

Please answer the following questions as best you can:

What is your system make and model?

How much RAM is in your system?

Have you ever used the Windows 'Hibernate' feature?

If you have a Dell computer, what is the Service Tag Number?

What is your XP Version and Service Pack?

Describe your current antivirus and anti malware situation:  Microsoft Security Essentials (MSE), McAfee, Symantec, Norton, Spybot, AVG, Avira!,  avast!. Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc.

Was the issue preceded by a power interruption, aborted restart, or improper shutdown?  (this includes plug pulling, power buttons, removing the battery, etc.)

Does the afflicted system have a working CD/DVD drive (internal or external)?

Do you have a genuine bootable XP installation CD that is the same Service Pack as your installed Service Pack (this is not the same as any Recovery CDs that came with your system)?

What do you see (exactly) that you don't think you should be seeing and when do you see it?

If the system used to work properly, what do you think might have changed since the last time it did work properly?

It is extremely unlike that your lsass.exe file is missing or needs to be replaced but you can sure try replacing it if you want.

The symptoms of a missing or corrupt lsass.exe file are as follows:

If the lsass.exe file is missing, you will see the Windows splash screen and then a moveable mouse cursor and that is as far as you will get.

If the lsass.exe file is corrupt, you will see the Windows splash screen and then a moveable mouse cursor and that is as far as you will get.

What you would normally see next is the "Windows is staring up..." message, but you will not get that far for your system is essentially halted.

With a missing or corrupt lsass.exe file, you will not be booting in any mode, no Safe Mode, etc. but you can sure try if you want.

There will also be nothing of interest the the Event View logs (assuming you look at them after you fix the problem) since XP does not get far enough along to begin logging any information.

Andrew E.  Here is a fun project for you:

Why don't you boot your system into the Recovery Console, rename your lsass.exe file to something else so the file becomes "missing" (rename  lsass.exe  lsass.xxx).

Then reboot your system and see what happens.

The describe how to fix the system with no CD/DVD drive and no genuine bootable XP installation CD.

Then you will have something good to put in your notes that will work for any similar situation.
