Server 2011 SBS - Operating System Reload / Active Directory Question

I have a Windows 2011 SBS server that had a hard drive go out in a RAID array which was causing random reboots and sometimes hard lockups. The OS is still functional but severely corrupted.  After many attempts to repair I have decided to reload the operating system. Active Directory and the file sharing are still functional for the users currently.

I am familiar with the reload of the OS, but I would like to be able to restore Active Directory and the domain settings so that when I take the server back from the reload that I won't have to go around and do anything to the workstations.  Any tips on how to make this happen?  I have a good backup of the Windows system state with Mozy, but can make additional backups if needed with Windows backup or whatever.  Just not sure how to restore everything after the OS is reloaded.  Thanks for your help!

You would have to carry out an authoritative restore to achieve this after you rebuild the machine.

**Make sure you can restore the server back to the current state incase you run in to any problems with your restore**

It is not that complicated or hard, just take it slow and pay attention to the details.  Below is a good article.  Good Luck

A safer solution to start (since you'd know if you would be successful from the beginning) would be to install another DC in the SBS domain.  Then, you would have a replicated copy of your AD.  You would reload the SBS system in a migration mode so it pulls over the AD and you have it preserved.  I WOULD make other backups first as a precaution.

If you have a spare box ... Lee is correct.

The to restore your Shares

1.       
Backup the following registry key (clearly do this ahead of time)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares

Save this as part of your disaster recovery kit and/or normal backup procedures
      
2.       
Recreate folders

Restore you data/recreate folders as they were
      
3.       
Import registry key

Import the saved registry key
      
4.       
Restart windows

Restart your windows server, when you log back in, the shares will be recreated and the permissions will be restored as well
