Question: How can I move DNS Zone Files from one server to another?
To move DNS zone files from one server to another, follow these steps:
Note: To use the following method, the Windows 2003 DNS Server service must be installed on a new Windows 2003-based server. The DNS Server service should not be configured yet.
- On the DNS server that is currently hosting the DNS zone(s), change any Active Directory-integrated zones to standard primary. This action creates the zone files that are needed for the destination DNS server.
- Stop the DNS Server service on both DNS servers.
- Manually copy the entire contents (subfolders included) of the %SystemRoot%\System32\DNS folder from the source server to the destination server. On the current DNS server, start Registry Editor (Regedit.exe).
- Locate and click the following registry sub key: HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\DNS Server\Zones
- Export the Zones entry to a registry file.
- On the destination DNS server, double-click each registry file to import the Zones subkeys into the registry.
- Bring the current DNS server down and transfer its IP address to the destination DNS server.
- On the destination DNS server, start the DNS Server service. To initiate the registration of the server's A and PTR resource records, run the following command at a command prompt: ipconfig /registerdns
- If this server is also a domain controller, stop and restart the Net Logon service to register the Service (SRV) records, or run the following command at a command prompt: netdiag /fix
- The standard zones that were previously Active Directory-integrated can be converted back to Active Directory-integrated on the replacement DNS server if it is a domain controller.
- Verify that the SOA resource records on each zone contains the correct name for the primary server and that the NS resource records for the zone(s) are correct.
Note: The steps outlined in this article do not migrate the following DNS server settings:
- Root Hints
- Any specific registry setting made under any keys other than the key that is specified in step 5 and step 7.
