How do I move my dns server from one machine to another?
If you transfer all the files from the default path C:\windows\system32\dns specifally all the zone files.
Then export the key values below to .reg files then move them and add them to the new machine you should be up and running in a flash.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DNS Server
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DNS
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DNS\Parameters
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DNS\Zones
