Windows 7 SBS BSOD c000021A

[azler]

I hope this is the right forum but I think my error is fairly generic across all the windows OS's.

I have found myself is a fairly irritating position.

My SBS 2008 server has failed and causing me a whole lot of pain in the process.
There was a fairly comprehensive backup plan in place, Acronis image (Daily), Windows image (Daily) and Bexec.
The last DA test we did worked fine and I was able to restore the acronis to a VM and boot.
Now we have actually had an error none of the backups work! All with the same error code on physical hardware and within a VM.
The error is:
Link Removed
Steps taken:
Restore to VM
Load SBS media to do system repair (It prompted for password for the user Administrator. Didnt know it as it was SBS with AD we used a different account.)
Load offline NT password, Enable Admin and blank password
Load SBS media to do system repair, sfc scan & chckdsk
Made some reg tweaks so it didnt restart when it BSOD (Still cant get it to make a memory dump though.)
All returned no errors and fine.
One restart the same error.
Tried all the F8 options, All with the same error. Even safe mode!
In safe mode it stalls at ClassPNP.sys and then straight to the BSOD screen.
This folder is empty:
C:\Windows\System32\catroot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\
& This one does not exsist:
C:\Windows\System32\
I copied these files from a PE environment to the C drive to at least try and get it to boot.

I have had to re-install the server from scratch to get it up and running but some settings I need fromthe VM as I just figured I would be able to restore from a previous backup.
Tried:
Chckdsk + sfc both completed detecting any errors.
I backed up the bcd and made a new one with bcdedit + figured out how to use the above two commands.
bcdedit /set {default} nointegritychecks on
bcdedit /set {default} testsigning on
Restarted same error.
Restored the original BCD and added the above two commands but still the same error.
I tried the article from HP and it hangs on CRCdisk.sys then goes to BSOD.
CRCdisk.sys points to a failed disk being the issue but how can this be so when its a VM?
Can I disable this from trying to load to bypass it?

I've been searching Google for an app to test backups for corruption but nothing has popped up so far... Perhaps Randy may know of something?

I did verify the backup with acronis after completion and it said it was fine..
Its strange the sfc / startrep wont work correctly though..

Similar to the System File Checker is the DISM Tool. This will, if possible, download files to repair missing or corrupt data. Opn the admin command prompt and type:
DISM /Online /Cleanup-Image /RestoreHealth
Press enter and await results.

Thats interesting I didnt know you could use that with server 2008.
Just mounted the VHDX file on widnows 8 and tried to run it from CMD:
DISM /Image:G:\ /Cleanup-Image /RestoreHealth
& Got a error about it not working on this type.

Dism is not part of the server 2008 build so I cant use it from the recovery cmd. Going to try booting from a windows PE environment and see if that works. If I boot to the PE environment will the /Online switch work or will it try to make changes to the PE environment?


/Cleanup-Image /RestoreHealth are not supported on server 2008 or Vista.

Can you initiate a OOBE from DISM? or from an offline state?

Hmm.. it says here that DISM will work with Server 2008:

DISM can be used to service the following operating systems:

• Windows 8.1
• Windows 8
• Windows Server 2012 R2
• Windows Server® 2012
• Windows® 7
• Windows Server 2008 R2
• Windows Server 2008 SP2
• Windows PE 5.0
• Windows PE 4.0
• Windows Preinstallation Environment (Windows PE) 3.0

It is supported by Server 2008 but the commands you can run are limited.

I do believe that /Cleanup-Image /RestoreHealth are for server 2008 r2.

I ram the command on a server 2008 R2 and that option is there on Server 2008 you just get the DISM is not recognised as a command.

Does anyone have any more tricks I can try to use to get past this problem?
I really dont want to give up on this.
