Creating Internal Root Servers Using Cache.dns

To configure your Windows NT DNS server to query internal root servers instead of the Internet root servers, follow these steps:

1. Stop the Microsoft DNS server using one of the following methods:
   • Use the Services tool in Control Panel.-or-
   • Type the following at a command prompt and press ENTER:net stop DNS
2. Use a text editor (Notepad.exe) to open the Cache.dns file, which is located in the %Systemroot%\System32\DNS folder.
3. Delete the Internet root server entries and add your internal root servers.
4. Save the file as Cache.dns and close the editor.
5. Restart the Microsoft DNS server service.

When you run DNS Manager and drill down into the Cache object of your DNS server, you will see the internal root servers listed. DNS Manager may show duplicate entries for the same record even though the zone file only contains the record once. This will not affect functionality.
