DNS Client - Windows Vista Service

The DNS Client service (dnscache) caches Domain Name System (DNS) names and registers the full computer name for your computer. If the service is stopped, DNS names will continue to be resolved. However, the results of DNS name queries will not be cached and the computer's name will not be registered. If the service is disabled, any services that explicitly depend on it will fail to start.

This service also exists in Windows 10, 7, 8 and XP.
