Configuring Windows 2000 to use local DNS server

First Double click the "Network and Dial-up Connections" icon in the Control Panel:


Then right-click the icon for the network connection and select "Properties" from the pop-up menu:


Then in the connection properties dialog, select "Internet Protocol (TCP/IP)" and click the "Properties button":


In the "Internet Protocol (TCP/IP) Properties" dialog, check "Use the following DNS server addresses", and enter the IP address of the local DNS server (*) as the "Preferred DNS Server":


Finally click "OK" both in the "TCP/IP Properties" and "Network" dialogs to save your changes.

(*) The DNS server IP address must match an IP address that Simple DNS Plus is configured to listen on in the Options dialog / DNS / Inbound Requests section.
If you are configuring the computer which Simple DNS Plus is running on, you can use (see below) - otherwise you must use an IP address which is accessible over the local area network.

NOTE: We also recommend disabling the "DNS Client" service

Windows 2000 and DNS server

If you try to enter "" as DNS server in the TCP/IP configuration of a Windows 2000 computer, you will get the following error message:

IP addresses starting with 127 are not valid because they are reserved for loopback addresses. Please specify some other valid value between 1 and 223.

This only happens in Windows 2000 and we have no idea why Microsoft did this. But they must have realized that this was a mistake because this doesn't happen in later Windows versions such as XP and 2003.

To solve this, we have created a small tool which can set the DNS server to on Windows 2000.
Simply download and run: setdns127.exe
