Implementing and Configuration DNS Server role: In our scenario we assigned computer name as champ. IP address is set to 172.30.10.1 and preffered DNS is given as 172.30.10.1. We are configuring Domain 'eihtech.com'.

We have successfully install DNS server on this machine.

Under DNS go to champ. Right click on forward Lookup Zones and select New Zone.

In Zone Name Specify eihtech.com



Zone File eihtech.com.dns will be created in Windows\system32\dns folder

Click on Finish



On completing the wizard Reverse Lookup Zone will be created.



Go to eihtech.com and create a New Host record.



Specify the name champ and IP address 172.30.10.1. select create associated pointer record checkbox.



One host record will be added in eihtech.com domain.

Similar one pointer record can be seen in Reverse Lookup Zone.



Command nslookup is used to verify DNS connectivity from network. You may assign IP address of same network to another computer on the network, assign 172.30.10.1 as Preffered DNS. And run nslookup command. Same output can be seen.
