Windows DNS Export/Import
Exporting / Importing Standard DNS zone records are relatively easy; just copy the zone (eg. orange.com.dns)
files from existing server (C:\WINDOWS\system32\dns) and place these
.dns files in the same location (C:\WINDOWS\system32\dns) in the target
(new) server, restart the DNS service and you are done.
Note: if you are hosting mix DNS record (AD and Standard) then copy zone file may not work. Your need to create empty primary standard domain in forward lookup zone and open this zone file from C:\WINDOWS\system32\dns and copy the contents from the source .dns file and reload or restart the dns server for refresh. .
Exporting AD Integrated DNS zone records:
Generally exporting AD DNS to files is recording purpose. We can build a new DNS server and all these record will be replicated.
Step 1. Mouse right click on the every zone record and click on
Export list….
Alternative (using dnscmd command)
F.Y.I – DNSCMD comes with the Windows Support Tools.
.zonename: orange.com
Export DNS zones:
Run REGEDIT and navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\DNS Server\Zones (Right-Click the key ZONES and export to a .reg file).
Alternatively, use command line: regedit /e c:\dns.reg “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\DNS Server”
Now copy *.dns from: %windir%\system32\dns
Note: you can put above regedit /e command to script and run as task to backup schedule time. Skip cache.dns as this contains cached DNS lookups.
Import DNS zones:
To import on Server 2003 or Server 2008, first create a test zone such as testdomain.com. The DNS server needs one zone created, but you can remove it after the import.
Copy the .DNS files into %windir%\system32\dns on the new (target) server.
Next double click on the .reg file you created to load all the zones into the new server’s registry (For Windows 2008: Right click the reg. file and run as Administrator)
Now, restart the DNS Server service and open the DNS manager. You are done.
