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. I have included the Packet Tracer activity file for you to download as well as the instructions below.

Question:
Im confuse if this webserver & name server is the same?
I guess my webserver answer is wrong.
can u explain how to determine the webserver and nameserver?
TOOLS:
ping
nslookup
tracert
mail.initech.com to get the ip address – for email ip add am i correct?
You got the webserver and nameserver ip addresses backwards and your mail server address is correct! Great job!
I am racking my brain trying to figure out how to get the ip addresses to the servers when they are locked and i cant view them in mac table, int bri, or anything. can you please show how to get the ip addresses for the servers?
So the nameserver is easy. That’s the DNS server, and you can see that in the IP Configuration tab for the one machine that’s already working (PC0), which can ping initech.com and danscourses.com at the start. If you look at PC1 and PC2, they have different DNS server information entered and cannot ping the various pages.
For the mail server, you can use an educated guess that the subdomain is mail.initech.com, and then do an nslookup on that name. It’ll return the IP of the relevant servers. Same deal with initech.com and danscourses.com.
How did you find the subdomain of the mail server?
3. What is the IP address of the Initech webserver?
192.168.5.110
which can be found with ping initech.com
4. What is the IP address of the Initech Nameserver?
as pc0 can reach dns server and not pc 1 and pc 2 so its dns server it correct which is 192.168.5.111
name server
I think that the WAN interface address is 200.222.22.5

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.
This site is really awesome, I’ve learned a lot buy watching Dan’s tutorials on youtube. But does Dan post solutions for this specific network activity? I’m a newbie and I’m just starting to learn CCNA. I’m planning to take the CCNA exam and I would really appreciate if someone could educate me.
I have not tried the lab yet but if you go to the switch DMZ to the servers and use the show arp command and the table should show mac addresses and ip address
Hello DAN. You are the Boss like Jeremy Ciora of CBTnuggets. What a great way to learning Networking
