Replacing a failed 2008 R2 domain controller
We have three domain controllers in our 2008 R2 domain. Once of the servers failed -- ad02. Everything is still operating fine in the domain of course because of the other DCs still operating. We would like to replace the ad02.
My thinking was that I would install the OS on a new server, patch and service pack it, then reset the AD02 computer account, add the new computer to the domain as AD02, install AD and DNS on it (dcpromo) and be done with it.
Is that the proper procedure?

While you CAN perform a manual metadata cleanup, if your DC is 2008R2 or later, you can just delete the computer account in the domain controllers OU - that now should perform the cleanup for you.
More important question - WHY do you have 3 DCs? Do you have more than 4000 employees? Do you have 2 or more sites where each site has at least 20 people?

Qty 3 DCs - 1 physical, 1 Virtual and 1 spare virtual because we are paranoid.
You should have more than 1, but having 3 is excessive. If one fails, the other handles things fine... if BOTH fail, that's why you have backups. I'm paranoid too, but three is excessive unless you have multiple sites and/or a HUGE organization.
