System File missing or corrupt

My Win2K system will not boot. After splash screen, blue
screen appears with three line message that flashes by
and the boot starts over. This is an endless loop. The
most I can get from the message is that a system file is
missing or corrupt. Apparently, this has something to do
with the Access Control software I purchased in early
July.

I tried booting in Safe Mode, and the system does the
same thing. The last file that loads successfully is
WINNT/SYSTEM32/DRIVERS/AGP440.SYS. Can anyone tell me
from that what file is missing? I also have another
problem ... Win2K CDs are missing. Is there any way to
get this file from another source?

Thanks.

If the system hive is corrupt, and assuming you already tried LKG, It may be
possible to rename the system hive found in
%windir%\system32\config\system
to system.old
then rename
%windir%\system32\config\system.alt
to
%windir%\system32\config\system

You can also try using the most recent backup found in
%windir%\repair\regback

If that fails you haven't much choice but to copy/ use the
original-as-installed system hive from
%windir%\repair\system
to
%windir%\system32\config\system
You'll need to reinstall the device drivers for any hardware added since the
original OS install.

To start the Recovery Console, start the computer from the Windows 2000
Setup CD or the Windows 2000 Setup floppy disks. If you do not have Setup
floppy disks and your computer cannot start from the Windows 2000 Setup CD,
use another Windows 2000-based computer to create the Setup floppy disks.
Press ENTER at the "Setup Notification" screen. Press R to repair a Windows
2000 installation, and then press C to use the Recovery Console. The
Recovery Console then prompts you for the administrator password. If you do
not have the correct password, Recovery Console does not allow access to the
computer. If an incorrect password is entered three times, the Recovery
Console quits and restarts the computer. Note If the registry is corrupted
or missing or no valid installations are found, the Recovery Console starts
in the root of the startup volume without requiring a password. You cannot
access any folders, but you can carry out commands such as chkdsk, fixboot,
and fixmbr for limited disk repairs. Once the password has been validated,
you have full access to the Recovery Console, but limited access to the hard
disk. You can only access the following folders on your computer:
%systemroot% and %windir%

I cannot get to a DOS prompt to do any renaming, file
browsing, etc.

I'm going to see if I can get startup CDs from a friend.

Thanks very much for your detailed reply. I have printed
and am off to try and resolve.
