My DC crashed this morning (Hard Drive Failure) I Had a new server to replace the DC. I can access the old DC's hard drive from a windows box. Is there a way I can make the new server a DC with system state backups? and or AD database files?

Thanks
Josh

Hi Josh,

What's the Operating System of the crashed Domain Controller, and the new Server.
Secondly, do you have a system state or any backup of the old domain controller.

In windows 2003, the /adv switch can be specified with dcpromo, when promoting a server to host active directory.
This switch would tweak the dcpromo process to use the existing AD files from a backup taken off a different Domain Controller, extract all the required data from the se files and promote the new server.

Following is an article that might come in handy

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

A few questions josh, before i can make any suggestions about roles and other configuration changes.

How many DC's are part of the domain, i mean to ask if there are any other working DC's in the environment after that particular DC crashed?

Do the crashed DC and new server have same hardware (right down to same Disk Controller, NIC, Processor, MBD, etc)
, same OS level and Service pack.

Do you intend to resurrect the crashed DC, or want to remove it completely and permanently off the network.

There was only 1 DC in this domain. The new server is a completly different server.

Yes we will reseruct the old server and continue to use that as the domain controller

Thanks

Hey Josh,
what i understand is  - Crashed DC was the only DC in the domain.

If this is the case, it really does not leave us with many options.

The best bet would be to get the crashed DC to a working state trying to restore the system state backup,
This backup wouldn't really be helpful trying to build up a new DC owing to
  - Hardware differences between the 2 servers, that means system state backup cannot be restored
  -  /adv switch is only used to promote to an additional domain controller.

hey Josh,
Unfortunately, the AD database/log files from crashed DC's sysvol folder aren't really quite helpful building a replica domain controller.
These files are server specific, so copying off these files from the crashed DC and attempting to reuse them on a different Server..this might not work.
