(http://support.microsoft.com/kb/256986/EN-US/ )Description of the Microsoft Windows Registry
If you are using Windows XP, the DNS Client service may not revert to using the first server in the DNS server list.
This behavior occurs because the Windows XP DNS Client service (Dnscache) follows a certain algorithm when it decides the order in which it uses the DNS servers configured in the TCP/IP properties. If the DNS server list is reprioritized, the Windows XP DNS Client service resets the server priority at periodic intervals. By default, the server priorities are reset every 15 minutes.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To work around this behavior, modify the registry so that the DNS server that is configured first is tried first on each query. Follow these steps, and then quit Registry Editor:
