How does flushing a DNS cache help resolve some issues, and while you’re at it what’s DNS?

//
I suddenly started to encounter ‘time-out’ error messages with certain sites – yours being one of them! On looking further, I could not find any logic to the dozen or so sites I regularly visit being unavailable. I tried accessing these sites through an online proxy – the sites loaded. I re-booted and ran all the adware / spyware / virus programs – all to no avail. I managed to Google the problem and found some obscure forum with the response ‘go to command line prompt and type “ipconfig /flushdns” ‘ which I duly did. Perfect – problem solved – but why did I need to do this, what is a DNS cache flush and how can I avoid this problem in the future?

Well, I can’t really say why that fixed your problem, since a reboot is also another way of flushing your DNS. In fact, it’s one of the many reasons tech support folks insist you reboot as the first step when investigating just about anything.

But you seem to indicate that a reboot actually didn’t help.

However, flushing the DNS cache can sometimes help, and it’s much faster than a reboot.

How Do I Schedule a Nightly Reboot in Windows 8.1? (with video)

Win 8, I would like to know how to use task scheduler to shut down my computer at a certain time each night. I cannot figure how to accomplish this. On my old XP I used a program called Jit (just in time) because I could not use Task Scheduler then either.

Well, Task Scheduler is absolutely the way to go here.

As it turns out you have everything you need already included in Windows, and while I’ll show you for Windows 8.1, this approach should work with almost any version from XP on.
