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.
|Windows Vista edition||without SP||SP1||SP2|
|Display name:||DNS Client|
|Path:||%WinDir%\system32\svchost.exe -k NetworkService|
DNS Client logs on as NT AUTHORITY\NetworkService and runs in a shared process of svchost.exe. If DNS Client fails to start, the error is recorded into the Event Log. Windows Vista startup proceeds, but a message box is displayed informing you that the Dnscache service has failed to start.
DNS Client will not start, if the NetIO Legacy TDI Support Driver service is stopped or disabled.
