DNS (Domain Name System) is a simple idea that is far under utilized in every sized business.  This article will be less about DNS as a technology and more about practical application of that technology.  Many of the ideas have been simplified to help with gaining a 30,000 foot perspective.  DNS is used in just about every aspect of networking in the IT world...e-mail delivery, file server access, disaster recovery, web surfing, remote access, you get the idea!

Troubleshooting is such a day to day activity, inside and out of IT, that most of us never think twice about it.  For example, if your TV isn't turning on, most of us will check the remote first to be sure that the batteries are good.  Next, we'll usually try turning the TV on with the button.  And if that doesn't work, check the power cord to see if it is plugged in.  There you have it, troubleshooting 101. These steps can be used to troubleshoot anything, not just in the Information Technology industry.
