Internet connection problems? DNS cache corrupted? Facing DNS issues or problems? Maybe you need to flush Windows DNS Cache. If your computer is finding it difficult to reach a certain website or server, the problem may be due to a corrupt local DNS cache. Sometimes bad results are cached, maybe due to DNS Cache Poisoning and Spoofing, and therefore need to be cleared from the cache to allow your Windows computer to communicate with the host correctly.
Typically, there are three types of caches in Windows 11/10 that you can flush easily:
Clearing the Memory Cache can free up some system memory while clearing the Thumbnail Cache can free up space in your hard disk. Clearing the DNS Cache can fix your internet connection problem. Here’s how you can flush the DNS cache in Windows 11, Windows 10, Windows 8 or Windows 7.
Flush DNS Cache in Windows 11/10
To flush the DNS Cache in Windows 11/10 you need to:
- Open an administrative command prompt window as an administrator
- Type ipconfig /flushdns and hit Enter
- You should see – Windows IP Configuration. Successfully flushed the DNS Resolver Cache
- Exit CMD
- Your DNS cache should have been reset.
Let us see it in a bit more detail.

Disable DNS Cache
If for some reason you wish to disable DNS caching, type services in start search and hit Enter to open the Services Manager. Here locate the DNS Client service.
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.
Double-click on it to open its Properties box. Here change its startup type from Manual to Disabled. If you disable the DNS Client service, DNS Lookups may take longer.
