Network Troubleshooting PT Activity

Overview

It is important to know how to troubleshoot network connectivity issues. How to configure PCs to add them to the network? What tools can you use from the command prompt to test connectivity and check your network address settings? In order to test your skills, I created a Packet Tracer 6.1 activity in which you are the network administrator and you need to troubleshooting the network and answer some fundamental questions about the network.

      Do you have still any questions natyra? Getting the IP of the mailserver was a little bit tricky. Me and my colleague tried a lot of thins but everything is disabled in this lab. So you have to use the hint and guess, that the domainname of the mailserver is mail.initech.com. Than you can resolve the domain.
