Read-only domain controllers and disaster recovery
I'm planning to move our backup server from $current_remote_location to $other_remote_location_that's_better_suited.
As part of that (and a larger planned 2008R2 upgrade) I'm pondering the benefit of adding a lightweight rodc to the mix. I'm aware I'd have to pre-cache passwords and any locked out accounts would stay that way until it spoke to a writeable dc. But it would mean faster appropriate access to anything I can make available from backup.
Anyone done/planned this? Is it worth it? It would mostly be a time cost (re-used hardware).
