NTOSKRNL.exe replaced, now Win2k always reboots on startup (even in Safe Mode)

I originally had a Stop error with the NTOSKRNL.exe file missing or corrupted. I was unable to go into the Recovery COnsole due to missing Administrator password (did not match system password). I copied a new NTOSKRNL.exe from another box and copied it onto the broken machine. The computer now boots up, but reboots every time after the final Windows splash screen loader. How can I recover this box?

FYI - this box was originally upgraded from Windows 98 and has been runnign fine for over 1 year.

Regards,

Erik

"3920 » How do I perform an in-place upgrade of Windows 2000?

If a repair does NOT cause your computer to operate normally, you may wish to try an in-place upgrade, a last resort before reinstalling. The in-place upgrade takes the same time as a reinstall.

To perform an in-place upgrade:

1. Boot the CD-ROM (or boot disks).

2. Press Enter to install a copy of Windows 2000.

3. Accept the License Agreement.

4. If setup does NOT detect a your installation, an in-place upgrade is NOT possible.

5. When prompted to repair the existing installation, press R. Setup will perform an in-place upgrade"

"4508 » What does a Windows 2000 in-place upgrade change and not change?

I described performing an in-place upgrade in tip 3920 » How do I perform an in-place upgrade of Windows 2000?

When you perform an in-place upgrade:

1. Service Packs, hotfixes, and IE upgrades are rolled back.

2. Default registry values are restored.

3. Default permissions are reapplied.

4. COM and WFP are reregistered.

5. Plug and Play devices and the HAL are re-enumerated.

6. Drive letters are changed based upon the current drive and partitions. See Q2324048 - How Windows 2000 Assigns, Reserves, and Stores Drive Letters.

The following is NOT changed:

1. Installed components and programs.

2. Passwords.

3. Third-party registry entries.

4. The computer's role.

NOTE: If you upgraded your computer from Windows NT 4.0, profiles were stored at %SystemRoot%\Profiles. The in-place upgrade creates a \Documents and Settings folder and changes the registry profile to point to it. To fix the problem, use the Registry Editor to navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. For each user, there will be a SID sub-key and a Value Name of ProfileImagePath. Change the string value to point to %SystemRoot%\Profiles\<UserName>."

I replaced the NTOSKRNL.exe file inthe Windows\System32 folder. Is there another place where the "dll cache" can be found?

Thanks,

Can you try emailing me a .zip version of the NTOSKRNL.exe file for Win2k SP4 (just rename the extension and I will rename to .exe)? The one I pulled off was from a non-production Win2k server.

A "dll cache" folder does not seem to exist in the Windows\System32 folder. Any ideas? There are no folders hidden.

Look here

WINNT\System32\dllcache

Netman66

I don't have a Windows 2000 SP4 machine here - sorry...

If you can get the SP4 Network install, you can extract all the files to a folder on any machine. Then either copy or extract (depending on whether the files are still compressed) the file you want to a floppy disk.
