www.BlackViper.com: Windows Vista Service Pack 1 Services 411 - DNS Client

DNS Client

Default Description:

The DNS Client service (dnscache) caches Domain Name System (DNS) names and registers the full computer name for this 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.

Additional Information:

If you attempt to "repair" your network connection and a dialog box complains that the "DNS resolver failed to flush the cache," this service is the reason.

Only in extreme situations should you disable this service as caching DNS lookups reduces network traffic and makes internet surfing performance faster.
