LSASS.EXE 0xc00000f Windows 2000 server.  Critical server!!!!

Hi,

Our dc decided to crash and upon boot we get the following error:

lsass.exe system error.  Directory services could not start due to the following error:  system cannot find file specified.  error status 0xc00000f.....

When we reboot to directory services mode we can see the lsass.exe file in the system folder and also the ntds.dit file in d:\ad\dbase\

I have read that this issue is due to a corrupt ad so I booted our other dc into ds mode and copied the ntds.dit file to the corrupt server.  However upon reboot I get the same error.  (I renamed the existing ntds.dit file ntds.old).

Has anyone any suggestion as to what I can try next??  The server is our exchange server so its pretty critical.

Many thnaks

I am quite certain it was not a virus as it happened whilst we were stopping the internet information store.

The server is also protected with sophos which updates every 2 hours.

But I will check...

Not a virus.. A worm! And any AV can experience a glitch..

If the LSASS.EXE itself is corrupted i guess you could fix it with a "SFC /SCANNOW" But thats quite a big job on a DC with Exchange..

I tried copying lsass.exe from our other domain controller but got the same result.

Our server is behind a managed firewall with all patches installed.  It may just be a coincidence that it happened when it did.

I will check for the worm..

If you get the system to boot you should check taskmanager for LSASS, if its there you got worms..

Got server to boot again..

Was not a virus but a corrupt AD as initially thought..

Firstly booted into D/S mode and tried to run ntdsutil but crashed out.  Then tried esentutl with the following structure:

esentutl /g "path\ntds.dit"/!10240 /8 /v /x /o

This showed a corrupt database so ran:

esentutl /p "path\ntds.dit" /!10240 /8 /v /x /o

This repaired the AD and then I had to delete the AD log files before booting back.

Server came back (5 mins ago) so will check whats happening.  As I type my outlook tells me the connection with the exchange server has been restored.
