Disaster recovery of Active Directory in SBS 2003 on new hardware platform

I am working with a failed server that was utilizing SBS 2003 and mirrored drives. The old server experienced a catastrophic failure and as a result corrupted the mirrored array. Utilizing HDD recovery software, I am able to pull the System State information from the old server as well as many of the files.

I have a new server with entirely different hardware that I have installed SBS 2003 on using the clients original software CD's. The OS is installed, the machine name is the same as the old server and all of the domain information is the same.

Can I pull the Active Directory information from the salvaged files and import the data to the new server? Will this allow all of the existing workstations to log in as they did prior to the failure using the existing user ID's and computer names?

I understand that I need to reinstall programs and data files, and I'm not concerned with that aspect, but I would like to save time with the AD component if at all possible so that I don't have to recreate all of the users and computer accounts.

Hi SWTHOMAS,

you are in luck that you have a usable System State backup to use. It contains all the necessary information to restore your Active Directory including user and computer accounts. Just restore it to your new server using Windows Backup and you are back in business. Different hardware does not matter.

Actually HAL and ACPI is important to be same jhautani.
Install the same windows (same source) in same drive and folder, then without setting anything in your new installed windows, just restore the system state and restart. If the OS behaved abnormal and you couldn't get along with it, there is another Microsoft technical  approved way:
- Install a new Windows. The source and the drive is not important.
- Restore you system state backup in another place. You can choose this option (another location) in Advanced setion.
- Run dcpromo /adv
- Select An additional DC for an existing domain option.
- Select install from a restored backup
- Browse to the folder you have restored your backup
- complete the installation
- Restart and Install DNS, Create 2 Primary zones: _msdcs.yourdomain.com & yourdomain.com
- Seize all master roles
- Make your DC as a GC
Ask for more inf. if needed.
Good Luck

Different HAL: By default, the Hal.dll is not backed up as part of system state, however the Kernel32.dll is. Therefore, if you try to restore a backup onto a computer that requires a different HAL (for example, to support a multiprocessor environment) compatibility issues exist between the new HAL and the original Kernel32.dll. To overcome this incompatibility, manually copy the Hal.dll from the original computer and install it on the new computer. The limitation is that the new computer can use only a single processor.

Incompatible Boot.ini File. If you backup and restore the boot.ini file, you might have some incompatibility with your new hardware configuration, resulting in a failure to start. Before you restore it, ensure that the boot.ini file is correct for your new hardware environment.

Different Network or Video Cards. If your new hardware has a different video adapter or multiple network adapters, then uninstall them before you restore data. When you restart the computer; the normal Plug and Play functionality makes the necessary changes.

Disk Space and Partition Configuration. Partitions on the new computer must match those on the original computer. Specifically, all the drive mappings must be the same and the partition size must be at least equal to that on the original computer.


Hope this help!

I am getting ready to look into several of these solutions.

Snusgubben: the first link you provided is for Server 2000 products. Will it work with SBS 2003?

Disaster recovery is the same on Server 2000 and 2003 (including AD), so the link for Server 2000 should work for SBS 2003 also.
