An explanation of the DNS Client (Dnscache) service in Windows 7.
What does the DNS Client (Dnscache) service do?
The DNS Client (Dnscache) is responsible for resolving and caching domain names. When you are browsing the Internet and type www.google.com the Dnscache service finds (also known as resolving) the exact location (IP address) of google.com and then keeps a copy of its location for a short time.
DNS Client (Dnscache) service details
- Service name: Dnscache
- 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.
- Path to executable:
C:\windows\system32\svchost.exe -k NetworkService
- Startup type: Automatic
Does my computer need the DNS Client (Dnscache) service?
Your computer doesn’t need the Dnscache service to run, but Internet and network access will not work if it’s disabled.
Should I disable the DNS Client (Dnscache) service?
First off, I have to say that it’s best to leave service optimization up to Microsoft. With that said; I would leave the Dnscache service alone.
