Domain controller failed beyond the recoverable point. Now that we have a new server running WIndows 2008, would I need to recreate all of the users to join the domain for AD to work? What would be the best approach?

This question came from our site for computer enthusiasts and power users.

You didn't back up the DC!?!? If this was my company it would be time for a new systems admin. Just so there is something useful in this comment: directory restore mode didn't work? – Not Kyle stop stalking me Mar 1 '11 at 19:27

If you don't have any backup and that was the only domain controller in the domain, then you can't recover it and you have to accept this fact; next time, you'll know why it's considered best pratice to have at least two domain controllers :-)

That said, the situation is not good at all: even if you re-create the domain from scratch using the same domain name, the new domain would still be a completely different thing from the old one (a domain is identified by much more than its name, which can actually be changed); there's no way member computers are going to recognize it: you'll have to remove them from the old domain and join them to the new one, even if they have the same name.

The same is tue for user accounts: the ones you create in the new domain will not be the same you had in the old one, even if their names and passwords match; so your users are going to get new user profiles when logging on to the new domain, and you'll have to re-assign permissions on every network resource.

And I seriously hope you aren't running Exchange, or things are going to get interesting...
