How to Remove Your DNS in Windows XP
When your computer's network settings were first configured, a DNS--or "domain name server"--address may have been entered manually. This can occur when you want to use DNS servers that are different from those provided by your Internet service provider. If you need to change these settings to remove the DNS from the settings in your Windows XP computer, you don't need any advanced computer expertise and it only takes a minute or two.

Click "Start," click "Run," type "CMD" in the Run box and click "OK." In the Windows Command Prompt window, type the following command and press the "Enter" key: "IPCONFIG /RELEASE." Once this command has completed, type the following command and press the "Enter" key: "IPCONFIG /RENEW." This process will renew your IP address. Finally, type the following command and press the "Enter" key: "IPCONFIG /FLUSHDNS." This final command will flush the DNS cache on the computer and force it to relocate DNS servers, which it will acquire automatically instead of using the ones that were previously configured.
