Restoring DC Shadow Copy Components following HOWTO guide does not work...

Hi all,

I am having a major problem where my DC has died and I restored the C:\ and Shadow Copy Components no problem, but when I rebooted, the DC just got stuck in the reboot loop.  I am using NetBackup 6.5.3.  I had a DC that crashed today.  The DC is a Windows Server 2003 x64 bit.  I followed the exact directions below given in the HOWTO and also the "During a System_State restore..." documents.  I mean, I followed those directions perfectly.  I ran the w2koption before I started the System State  (SCC) restore, restored System State (which restored successfully) and then ran the w2koption again after the System State restore.  I then rebooted the machine as directed by the documents, and now the server is still stuck in a reboot loop.  I cannot access the desktop via Safe Mode or Last Known Good Config...following both sets of directions led me to no where and now I am back to sqaure 1 where I am looking at having to install the OS again (actually I reinstalled the OS last night, and am now a little leary to following these instructions again seeing that they didn't work last night).  Any other ideas to follow than just these two documents below?  By the way, I restored the C:\ and System State (Shadow Copy Components) to the ORIGINAL hardware, so following the w2koption was a must to run.  I'm afraid that if I restore both the C:\ and System State and SKIP the w2koption, it'll just go back into its reboot loop.  Please HELP!  By the way, the server is a Dell PowerEdge 2950.  Does anyone know how to tweak that registry key to allow those components to be restored other than having to run that w2koption?  Any ideas are greatly appreciated!  Thank you, thank you, thank you!  :)

Documents followed below:

• HOWTO: Use NetBackup to perform a restore for a total and complete recovery of Windows XP, 2000 or 2003 client(s) that includes C: (and other system) drive(s), Shadow Copy Component, and/or System_State from a reliable full Windows-NT backup without IDR or BMR in the event of a Disaster (or need to fall back to a known working state).

• During a System_State restore, not all of the registry keys are recovered, causing the system to go into a reboot cycle.

By default, a System_State restore will not restore all the registry keys from the system that was backed up. There are specific keys that specify registry keys that are not to be recovered. This is done to ensure that after the reboot is complete after the restore, the system will reboot. The assumption is the hardware the restored data is going to is different than the hardware the backup job was done on. The following registry key determines this:
 
HKLM:\System\CurrentControlSet\Control\BackupAndRestore\KeysNotToRestore.
 
For more information on this, see TechNote 240980 in the Related Documents section below.
 

In order to change this default behavior, it will be necessary to run the w2koption. This is an executable that is included with NetBackup. This set of instructions assumes that the restore is going to a PC with exactly the same hardware as the PC that contains the backup information.
