Hello there. Welcome to this course titled Network Troubleshooting and Tools. I'm excited to get started showing you how you can use simple tools. Does troubleshoot network issues. This first lesson We're just gonna be covering the basics of the course and introducing your instructor.
And speaking of your instructor, let me introduce myself. My name is Jeff Brown. I've been a system administrator primarily working in the Microsoft space, with technologies like Windows Server Exchange Server, Skype for Business Office 3 65 and Power Shell. I hold several certifications, including Microsoft's M. C S, A and M C S C, as well as a few azure certifications.
I enjoy hiking and visiting national parks, as you can see in the pictures on the right.
If you have any questions about this course or just want to chat about technology subjects, you can find me at my blawg at Jeff brown dot tech or on Twitter at Jeff W. Brown.
But enough about me. Let's get into what this course is about and who does. Four.
This course is for anyone that works in I t help desk system administrators, network administrators and even developers. I believe the skills I'll be showing you here can benefit anyone working in 90. Knowing how to identify and troubleshoot networking issues is a core skill everyone in I T. Should know.
In order to be successful in this course, I would recommend that you already be comfortable working in the terminal or command prompt.
Nearly all of the tools and techniques will be using are found in the command prompt.
For this course. I'll be working inside of Windows 10 and Server 2016. But many of the tools are also found in Mac OS or Lennox or have equivalent commands available. I would also recommend that you understand how I P address notation works. For example, if a computer has an I P address of 192.168 that 1 25
followed by a slash 24. This means the subject mask is 255.255 dot 255.0 Another Pre Brexit would be knowing some common ports and protocols, such as Port 80 for http on Web servers or port 25 for SMTP or email servers. Finally,
I understand some different DNS record types, like a records or SRV records
for this course. Here are the learning objectives I have laid out for you. We're going to verify our network configuration.
Troubleshoot network connectivity,
verified domain name resolution,
modify roundtables,
test ports and protocols
will understand available advanced networking tools.
Finally, we'll understand how to install and troubleshoot network devices.
And here is a simple diagram of my demo environment and a couple of things that I want to point out before we get started. First on the left I have my server, 01 which is my Server 2016 server. It will be hosting a Web server and a simple SMTP mail relay
down below that I have are Windows 10 Workstation W eso won and I've identified these as green since they are virtual machines that I'm running on hyper V,
and each one is also sitting behind a virtual switch, which connects to a physical switch inside my environment.
From that switch, we can act out to my WiFi router combo and then connect out to the Internet.
This is just to give you an idea how I have things configured. You don't necessarily need everything in this diagram to use these tools I'm just trying to add a couple of things so you can see how they would work. Maybe inside your enterprise environment
that does it for this video. Like I said, it's just a quick overview of the course
introducing myself and where you can contact me if you have any additional questions.
Some of the prerequisites I think you should have before continuing. Just so you're successful in the course are learning objectives and how the demo environment is configured that doesn't forgiving started coming up next. Let's go take a look at how we're gonna test network and activity. See you in the next episode.
