"I see DHCP, DNS and AD (in that order), at least in a windows environment as step one of anything."
It gets _messy_ but I think it's worthwhile to write out in biz continuity plan how to function without DHCP, DNS, and AD.
Take my case: we sometimes had the tier 1 and 2 services (the unix-based ones at least) up _days_ before DNS and AD were available. In the real world the business can't wait for DNS and AD to have access to their tier one and two apps: customers are waiting for product.
Note that a lot of work went into getting the Solaris stuff to this point: in particular using ZFS and zones made the process or restoration a breeze. By the time of our fourth annual DR exercise, getting stuff up and running was essentially waiting for it to restore from tape, adjust for things like 'DNS y/n' and done.
