Inaccessible_boot_device after restoring Active Directory

[Ash Keval]

I am trying to Restore AD to a fresh windows 2000 advanced server. The hardwre is identical to the original DC. I am using ntbackup to restore. After the restore, I get inaccessible_boot_device. Any help will be greatly appreciated.
Thanks

hi,

Can explain the process of restoration.
can be done in many ways.
like dcpromo then giving the information of Dc backup that will built the server.

Q is how are we doing it?

Where as the error is concerend, which server we are refering to here.

I expect you have restored some files additional to AD and created system problems.

I forget the procedure but there are specific ways to restore AD, have a look on MS Technet.

[Ash Keval]

I am following the exact procedures from Technet and other Microsoft guidelines. I am doing a system state backup and restoring to an
ml 370 g1 server which is identical to the original DC.

How about in safe mode are we able to boot in that. I think there is somemiss configuration we are doing there.

[Ash Keval]

No, Can't even log into safe mode. I don't know what I am missing.

Hi Ash,

When you say identical, can you confirm that the raid controllers are exactly the same models on each servers PCI bus.

You can see the Smart Array model details when each server POSTS, you might also want to take a note of the Smart Array firmware version at this point too.

I.E does one server have a Smart Array 3200 and the other a Smart Array 5300 for example or do they have the same controllers but very different firmware versions? Normally the incaccessable boot device stop code (7B) is due to a disk controller driver issue but it may be firmware related. If it's firmware you could update/downgrade the other system to match.

I hope this helps.

Hi,

Refer to this link.

But i think it is some what related to controller only.

If you can move the controller from other server to this new server. that may be helpfull to confirm the same.

The 431 controller is the same with the same firmware on both machines. I even swapped controller cards. Still the same result.
It seems, as soon as I do the restore, I don't see the boot partition.
