Netbook Network

Many DNS clients will cache name resolution requests, similar to how web browsers cache pages – by temporarily storing website names, the process of looking up an address you’ve visited before is faster. However, occasionally a corrupted entry will be cached – this means that if you have a corrupted entry for Netbook Network, the site will seem to be down when instead it’s perfectly fine, due to the fact that the DNS cache entry isn’t mapped properly. Getting rid of it means waiting for 24 hours or flushing your DNS cache manually. Here’s a guide on how to flush your DNS in Windows to clear DNS cache, which may include bad entries that don’t lead anywhere.

Open the start menu and search for (use “Run…” in XP) “cmd” to open a command prompt window. Then, using the command “ipconfig /flushdns” your DNS cache will be wiped and you’ll see a confirmation message.

If you experience issues with your DNS cache frequently, you can turn off DNS caching permanently. Open the start menu again and search for (use “Run…” in XP) “Services.msc“. In the list of Windows services, scroll down to “DNS Client” – right click, and hit “Stop“. In the case you want to turn DNS caching on again, simply restart the service.
