dns_probe_finished_bad_config prevents you from accessing websites, causes issues with connecting to outside services. As the name suggests, this is a DNS related error. The function of DNS is to resolve/translate names so when your system cannot resolve or translate the address, you will get this error or DNS_PROBE_FINISHED_NXDOMAIN
Providers DNS unless it has been changed. I always recommend using public dns servers, which you should see in this guide as they are most active and have a 99% uptime. If you don’t understand, don’t worry, just follow the steps below.
To fix this issue, follow the steps below:
Download and run Reimage Plus to scan for corrupt files from here, if files are found to be corrupt and missing repair them and then see if the BAD DNS Configuration issue is resolved, if not move on to the manual steps below.
Hold Windows key and press R
In the run dialog, type cmd and click OK
When the Black Command Prompt opens, type the following in it and Hit Enter.
ipconfig /flushdns
This will flush dns cache. Which is sometimes, the cause when there is a change in the DNS and the system is looking up its local cache to take you to the websites.
Once this is done, Hold Windows key and press R again.
