I have a Windows 2000 Pro workstation in Windows 2003 domain. Originally it cannot boot into Windows and stops at the following error message.
Error Message: Windows could not start because the following file is missing or corrupt: \winnt\system32\config\sys
I searched the web and found the following article related to my problem.
Because this is not the new install and it runs ok for a few years, so I assume the system hive is corrupted, then I follow the steps in the article to use the default system file. In detail the following commands are done:
Use Windows 2000 CD to boot up and go into Repair Console.
cd system 32\config
ren system system.old
ren system.alt systemalt.old
copy c:\winnt\repair\system c:\winnt\system32\config
then I remove the cd and reboot it from the hard disk.
Now here is the new problem: it can boot further then the previous stage but reboots itself before it shows the login screen.
I press F8 key to bring up the boot menu. I tried all options except two and they behave the same reboot symptoms. It can boot into the login screen if I choose the 'Safe Mode' and 'Safe Mode with command prompt'. It seems that it does not recognize the 'correct' passwords for domain user and local user. So I use Offline NT Password Registry Editor tool to reset my local admin password.
Now I am able to login to the admin account of the local system. But the system still behaves the same way: automatically reboots before it shows the login the screen. I do not know what is installed or changed. I can not reinstall the system because the application on the pc cannot be reinstalled.
Q#1. Any way to find out what is causing the system reboots by itself?
Q#2. How to troubleshoot this (auto reboot) problem?
Thanks a lot.
