Additional Information
The workaround explains how to flush a computer’s DNS cache. When a computer visits a website for the first time, it stores the website’s DNS information in cache. The next time the computer visits a website, it looks in the cache to see if the website’s information is present to use. Flushing the cache removes all the information stored in cache, forcing the computer to find the new DNS information for the website.
