no startup due to ntdsapi.dll not found 2

[malagash]

I havea a friend with a relatively new (1 yr) Dell laptop running XPP. He shut down the computer and on restart gets the message

lsass.exe
ntdsapi.dll was not found

Will a repair install fix this. Will he lose any files / data as a result of such an install?

TIA

Lets do something less drastic than a repair install.

Restart the computer and quickly hit whatever key gets you into the BIOS setup. (Using hitting the Delete key). You should find a setting for Boot Order. Reconfigure this so that the CD-Rom device is first.

1. Start the Recovery Console:

2. It is the expand command we want to use. For this example I will assume that D: is your CD Rom Drive, so change the below to reflect your actual settings:

expand D:\i386\ntdsapi.dl_ C:\Windows\System32\ntdsapi.dll
exit

Now restart the computer. Set your BIOS boot order back to hard drive first.

Thanks Bill. I won't have access to the computer till morning but I shall try and get back to the forum.

Unfortunately no luck with

expand D:\i386\ntdsapi.dl_ C:\Windows\System32\ntdsapi.dll

I get the message

unable to create file ntdsapi.dll

The owner's somewhat desparate as his backup routine has not been very comprehensive.
All help appreciated

I should add that the window that opens when he starts the unit is titled

"lsass.exe Unable to locate component"
This application has failed to start because NTDSAPI.dll was not found

When attempting to expand the file from the CD you indicate that I should type ....dl_ vs. dll.
Why the underscore?

 

[malagash]

It wouldn't be Copy as opposed to expand would it?

expand D:\i386\ntdsapi.dl_ C:\Windows\System32\ntdsapi.dll

 

[linney]

malagash" raises a valid point. The underscore indicates that the file is a compressed file and that is the filename on the CD. When Setup installs that file it automatically expands (uncompresses) and it becomes a .dll.

"If you need to replace a file in your Windows XP Professional installation, you can use the copy or expand command in Recovery Console to extract the needed file from the operating system CD. Use the copy command unless you are extracting a file from a .cab file, such as Driver.cab. When extracting a file from a .cab file, use the expand command".

See the paragraphs

Extracting Files from the Operating System CD.
Using the Copy Command in Recovery Console.

If you are using some sort of backup rather than the real installation CD, use copy.

But I would use the original CD and Recovery Console.

Hi everyone: thanks for the replies.
i have done the following all from the recovery CD that shipped with the unit:

expand D:\i386\ntdsapi.dl_ C:\Windows\System32\ntdsapi.dll

copy D:\i386\ntdsapi.dll C:\windows\system32

expand cdrom:\i386\ntdsapi.dl_ %systemroot%\system32\ntdsapi.dll

i have had another suggestion to use the UBCD. I am looking at the possiblities there too.

I VERY MUCH appreciate the input but am now brain dead (permanent state accoring to the wife) so will return in the morning. Must admit, I am good from 5am to 5pm after which, that's it

Please pass along any thoughts you might have and I shall get back to you in the am.

On any machine does this exist on the CD you are using:

your_cd-rom_drive_letter:\i386\

Use explorer to look at the CD.

 

[malagash]

Yes Bill, it's there. I can see it by searching the CD on my machine

 

[malagash]

I can see ntdsapi.dl_

 

[bcastner]

This is making me angry.

Go back to Recovery Console.
Logon as Administrator.

ATTRIB -r C:\Windows\System32
Expand your_cd_drive:\i386\ntdsapi.dl_ C:\Windows\System32\ntdsapi.dll

Exit

Same message

unable to create file ntdsapi.dll

There is nothing wrong with either of these commands. I think it is time to examine the disk in some more detail. Here are a couple of ways of doing it:

a) Temporarily install the disk as a slave disk in some other Win2000/XP PC, then try to replace the file. Don't run
chkdsk straightaway - it might ruin whatever you have left.

b) Boot the machine with a Bart PE CD:

http://www.nu2.nu/pebuilder/

To make one you need this:
* The tool from the above site.
* A WinXP Professional CD (but no licence number)
* A CD burner
* About three hours of your time

A Bart PE CD gives you a WinXP-like environment to work in. It gives you full access to NTFS partitions, independently of what works on your current disk. To make one is a substantial investment in time and effort - it's what the professionals do.

 

[malagash]

I don't have an adapter to connect it to another machine (it's on the list of "have to get one".

Bart PE CD - I am in the midst of creating one right now.
It looks extremely in depth.

I shall get back when I have finished burning it but before allowing it to do anything.
Thanks Bill

Well after trying a couple of disks I find that using a Dell XPCD was problematic. I had my IBM disk and it worked fine allowing me to create the Bart-PE CD.
I have booted up the machine and searched the options available but really don't want to make a move without some assistance from an experienced user.
If someone could walk me through this with respect to needed operations to resolve the issues above it would be most welcome.

 

[malagash]

I have also made a copy of the UBCD which seems to be another version of Bart-PE.
I have run that and tried running Trend Micro System CLeaner
With that I am getting various messages which say

Windows was unable to save all of the date for the file c:\several to choose from. The data has been lost. This error... etc.

The one onscreen at the moment refers to C:\$Mft (a master file table). That sounds deadly!

Can anyone shed some light on this?
Thanks

PE Builder v3.1.3 comes with a number of plug-ins already available (stored in the pebuilder313plugin subfolder), which you can individually enable or disable, by clicking on the Plugins command button of the Main application window, and then using Enable/Disable button (from the Plugins dialog box).

Some of the more common ones, selected by default, are:

A43 File Management Utility: BartPE's incarnation of Windows Explorer, or rather (for those who remember older versions of Windows) File Manager, which it resembles more closely.

Use that feature to copy the file.

Or, Since BARTPe supports a Run and a CMD setting, you can use the commands discussed above if you feel more comfortable us DOS-like commands.

While the machine was sitting it kicked out to a BSOD with a stop 0x24 error.
I shut it down for the moment as I have to go out for a couple of hours but will restart the process on my return,
Thanks Bill
