Are you unable to browse the Internet because the DNS cache is corrupted? You need to flush the Windows DNS Cache if your computer cannot find a certain website or server. This may happen due to a corrupt local DNS cache. Caching let you access the internet fast, but at the same time, if bad results are cached, maybe due to DNS Cache Poisoning and Spoofing, then you will be unable to browse the internet. It is necessary to clear the cache from time to time to allow your Windows computer to correctly communicate with the host.
There are 3 types of caches in Windows that can be easily flushed: Memory Cache, DNS Cache, and Thumbnails Cache.
Clearing the Memory Cache to free up the RAM from your computer while clearing the Thumbnail Cache can free up some space on your hard disk. Clearing the DNS Cache will fix the internet connection problem.
