What happens when you get to work on Monday and four users are standing in your cube with network connectivity issues? Where do you start, and more importantly, what layer of the OSI model would you start at? In this video tutorial we take our first look at SECHNIK Networking Ltd. and our first four troubleshooting tickets. We see how the bottom-up, divide-and-conquer, follow-the-path, top-down, and spot-the-differences approaches can be used to quickly isolate the problem in your network. We also see how the fourth ticket signals us on the ‘compare-and-contrast/spot-the-differences’ being a good place to begin. Enjoy!
