had a soon to be client had their whole DNS tables wiped, both forward and reverse lookup and of course no backups. any thoughts on how this might of happened. this is more for curiosity. thanks.
Were these AD integrated zones? If so and there's no system state backup and no other domain controllers you may be out of luck. If these zones were not AD integrated then you should be able to find the zone files in the %SystemRoot%\System32\dns folder. Simply recreate the zones using the same zone names and Windows should load the zones from the existing files.
