www.BlackViper.com: Windows XP Service Pack 3 Services 411 - DNS Client

DNS Client

Default Description:

Resolves and caches Domain Name System (DNS) names for this computer. If this service is stopped, this computer will not be able to resolve DNS names and locate Active Directory domain controllers. If this service is disabled, any services that explicitly depend on it will fail to start.

Additional Information:

This service is not required for DNS lookups, but if it makes you happy to have it running, you may. 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. It is also needed if using IPSEC.
