SUMMARY

This article discusses the steps involved when moving the zone files from one Windows NT 4.0 Domain Name Service (DNS) server to another Windows NT 4.0 DNS server.

MORE INFORMATION

When you use the Microsoft DNS server, you have the option of starting the service using a boot file or using information that is stored in the registry. Use the appropriate section below:

Starting DNS Using a Boot File

When you use a boot file to start your DNS server, follow these steps to move your zone file(s) from one Windows NT DNS server to another Windows NT DNS server:

Note The following steps assume that you have installed the Microsoft DNS server service on the new Windows NT-based server and have not configured any information for it.

  1. From Services in Control Panel, stop the Microsoft DNS server on both Windows NT DNS servers.
  2. Manually copy the entire contents (subfolders included) of the %Systemroot%\System32\DNS folder from the source server to the destination server.
  3. Restart the Microsoft DNS server on the new Windows NT DNS server.

Starting DNS Using the Registry

When you are moving a single zone file, follow these steps:

  1. From Services in Control Panel, stop the Microsoft DNS server on both Windows NT DNS servers.
  2. From the source DNS server, copy the desired zone file <zone name>.dns from the following folder:

          %Systemroot%\System32\DNS
                            


    to the same folder on the destination Windows NT DNS server.

  3. Create the new zone on the destination server using the DNS Service Manager. Configure the zone as it was configured on the source server, either as a Primary or Secondary zone. The new zone must be created using the same zone file name as the original file.

    For example, if Sample.com.dns was the original file copied from the source server to the destination server, Sample.com.dns must be the name of the new file.

    Note If the computer name is different on the new server, the SOA and NS records in the reverse lookup zones may still have the old computer's name. These records should be manually edited to reflect the computer name of the new server.
  4. Restart the Microsoft DNS Server on the new Windows NT DNS server.

When you are moving multiple zone files, follow these steps:

Warning Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

Perform steps 1 and 2 on the destination Windows NT DNS server only:

  1. Using the DNS Manager create a sample primary zone, Sample.com. Creating the sample zone ensures that the DNS server boot file information has been written to the registry and the DNS server knows where the cache information is located.
  2. Using DNS Manager, delete the sample zone that you created in step 1.
  3. From Services in Control Panel, stop the Microsoft DNS server on both Windows NT DNS servers.
  4. From the source DNS server, copy the desired zone file <zone name>.dns from the following folder:

          %Systemroot%\System32\DNS
                            


    to the same folder on the destination Windows NT DNS.

    Perform steps 5 through 8 on the source server only:

  5. Start Registry Editor (Regedt32.exe).
  6. Go to the following subkey:

          HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS
                            
  7. Click Zones, click Registry, and click Save Key.
  8. Save this key to a location from where you can restore it to the destination server and close Registry Editor.

    Perform steps 9 through 14 on the destination server only:
  9. Start Registry Editor (Regedt32.exe).
  10. Go to the following subkey:

           HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS
                            
  11. Click Zones to verify that it is selected, click Registry, and click Restore.
  12. Locate the registry key file that you exported in step 8.
  13. Click Yes to the confirmation dialog and close Registry Editor.
  14. Restart the Microsoft DNS Server on the new NT DNS server.

Note The information transferred in the registry key maintains the names of the zones and keeps you from re-creating the zone names in the DNS Manager for every zone file that was copied.
