SBS2003 Domain Controller AD corrupt
Posted on 2010-08-27
I have a client running Windows SBS 2003 as their single server, domain controller, file sharing, printing, etc. It has been running for about 2.5 years now without issue. One of the disks failed last week so a repalcement was sent from HP. it is running RAID 5 so no loss.
They replaced the failed disk today and booted the server. The array rebuilt itself and all seemed well, but windows will not load. The error:
Security Accounts Manager initialization failied becuase of the following error: Directory Service cannot start. Error Status 0xc00002e1. Please click ok to shutdown and reboot into Directory Services Restore Mode and review the event log for more detailed information.
I rebooted into DSRM and the event log just showed me the same message, nothing else notable. I found an article on EE regarding this that pointed to MS KB 258062. I followed all the steps and the only thing notable is the AD is corrupt.
To further things, the client has no good system state backup which at this point is leaving me having to rebuild the domain, this isnt really a big deal since the AD was small, 10 clients and nothing special as far as GPO so I am ok with that.
The problem, and as a result my question is: How do I remove the AD to reinstall it and build a new domain for them? I cannot boot into normal mode as the error described above comes up and reboots the machine. While in DSR Mode I cannot run DCPromo to demote the server as it tells me to go to normal mode. this is my first like this. Any sort of detailed steps are greatly appreciated.
I am not in a position to reinstall windows as all their other data is on there, and naturally not backed up properly.
BTW, the lossy repair didnt help. I did find a old system state from 11 months ago, but that didnt work either.
