  • AD crash on SBS2003; possible to restore AD from 2003 DC?

    Hi -
    We have a SBS2003 server which crashed and AD is unrestorable from backup. Can we restore AD from the healthy 2003R2 domain controller? Links / steps / procedures greatly appreciated!

    Yes you can....just get the OS back up and health on SBS box, Join it as a member server in the Healthy DC domain ( ie the orginal domain)...You will have to do metadata cleanup of SBS from healthy DC first....and now promote the SBS as ADC in the domain and after promotion, transfer all the FSMO roles on SBS.

    YOu will get your AD back on SBS,....but other SBS component like sharepoint or Exchange ....will have to be rebuilt

      OK sounds great. I'm a bit surprised that it's possible to promote an SBS server in a domain, as SBS needs to be the PDC (or am I wrong?).

      And help me understand why Exchange needs needs to be rebuilt? The existing datastores won't mount after transfering roles back to the SBS server?

      Thanks again

        FYI - here are the KB articles to perform the required steps:

        http://support.microsoft.com/kb/332199/ to force AD demotion from the faulted
        server

        - shutdown offending SBS server; now it's just a member server

        http://support.microsoft.com/kb/216498/ cleanup metadata on existing healthy DC

        http://support.microsoft.com/kb/255504/ seize FSMO roles to the heathly domain controller

        - start SBS server and reinstall AD.

        - Move FSMO roles back to SBS using KB255504 as above, and then configure other services as needed (DNS, DHCP, etc)

        We haven't resolved the MSExchange problems but will post what we need to do to this thread
