no startup due to ntdsapi.dll not found

  cspgsl 18:26 02 Sep 2006

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

Tried the Recovery Console:
expand D:\i386\ntdsapi.dl_ C:\Windows\System32\ntdsapi.dll

Got the message
unable to create file ntdsapi.dll

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

Anyone have any suggestions?

Resintall XP over the top of itself by booting off the CD and using the repair feature, this usually leaves all of your non system files intact.

Thanks. I thought of that but, as itisn't my machine and without a backup copy of the data I am very hesitant in trying that one.

You are on the right lines but don't use
expand D:\i386\ntdsapi.dl_ C:\Windows\System32\ntdsapi.dll

copy D:\i386\ntdsapi.dll C:\windows\system32
It will ask if you want to overwrite the old file.Having done this to get mine working last week albeit with a different DLL, this way worked for me.

Thanks I'll give it a go.

Tried the copy but got
"The System cannot find the file specified"
The original install CD is in the D drive.

Try This Next.Load the Recovery Console. Once at the prompt, enter these commands:

cd %systemroot%\system32

copy dllcache\ntdsapi.dll

If that does not work try:

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

Two things to think about. It could be a Virus, As I have looked in Google. It is also a File used for Internet connection

When you say "cd %systemroot%\system32" I take it that you want me to get to "C:\windows\system32" ?

I can do that but can you explain "copy dllcache\ntdsapi.dll"


do you mean type the word "%systemroot%" ?
