Resolve the issue when PC cannot clear DNS Cache
What is DNS Cache? What are the tips to fix the issue when a computer cannot clear DNS cache?
DNS server the Domain Name System server does the main function of translating the domain name into corresponding IP address of the site. The user enters the name of the website that is the domain name in alphabets whereas these need to be converted to IP addresses which are numerical. All these translation work is done by DNS server and the entries that convert domain names to IP addresses are contained in the 'DNS Cache'. The Internet Domain Name System involves caching on both Internet DNS server and on the client system. This DNS cache facilitates in keeping the Internet synchronized as the IP addresses change or as new servers come online. Thus, the DNS Cache serves the server a lot.

Need to clear the Cache
The need to clear DNS cache occurs when it becomes polluted. In the sense when any unauthorized IP addresses or domain names are inserted into the cache, it gets polluted. Computer virus can also be a reason for the poisoning. So in order to clear it you need to flush the DNS cache to make it free from poisoning.
Reason behind the issue
Sometimes you may come across the message ”œUnable to clear the DNS Cache”Â. The main reason for this message to occur is when the DNS client service has been disabled. You can get rid of this issue by enabling the DNS client service and later on clearing the cache will end up in flushing the DNS cache.
In order to fix the issue initially you need to enable the DNS client service. For that you need to open the ”˜Services MMC plug in”™ under 'Administrative Tools' of 'Control Panel'. Next you need to find the 'DNS Client' service in the list and double click on it in order to enter its properties. Then you need to change the 'Startup Type' from disabled to manual or automatic followed by clicking on 'Ok”™. Finally you need to reboot the system to finish the process.
