Summary of steps for backup and restoration of Windows Server DNS Server

1. Stop the DNS Service (execute the command: net stop DNS during running)

2. Open regedit and find HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ DNS.

3. Export the DNS branch. Named dns-1.reg

4. Find HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ WindowsNT \ CurrentVersion \ dnsserver

5. Export the dnsserver branch named dns-2.reg

3. Copy the *. DNS File backed up earlier to the % SystemRoot % \ system32 \ DNS \ folder of the new system.

4. Disable the DNS service.

5. Import the dns-1.reg and dns-2.reg of the backup to the registry (if the machine name is different, replace the machine name in the Registry file .).

6. Restart the DNS service.
