Windows 2003 server will show the loading screen then it stops with:
Stop c000218 registry file failure or corrupt. The registry can not load the hive \systemroot\system32\config\security
Then it start a count down about dumping the physical memory to disk and reboot itself again.
I found Error starting Windows SBS 2003 - STOP: c0000218
But the config there is different directory than mine. Is it the same step to try for recovery console?
Booting to the recovery console to run chkdsk is an "option". However, the likely-hood of this actually fixing a problem is almost 0, so not a good option. The correct way to fix this problem is to restore from backup or reinstall Windows.
