When there are any problems with the system related to the internet connection, the users execute the command to flush the DNS cache memory or stop the DNS. Some other users also flush the DNS cache if it gets corrupted or if any kind of DNS settings issues in the system.
Many Windows users have reported lately that when they tried executing the command for stopping the DNS client service, it threw an error message that said “The requested pause, continue or stop is not valid for this service” and the command did not get executed.
Since they were not able to execute this command, the issues related to DNS remained in the system without getting resolved.
Whereas the flush DNS cache command executes perfectly for some users. But after a recent windows 11 upgrade and Windows 10 21H1 version, no users are allowed to stop the DNS client service using the command net stop dnscache.
In this article, we are going to show you how to resolve this issue so that the users can stop the DNS client service.
