Implementing Conditional DNS Forwarding

**In this Video: **

• We will illustrate how DNS Conditional Forwarding can be implemented in your organization.
• We will consider a common scenario in which DNS Conditional Forwarding can be deployed.
• At the completion of this lecture you will gain valuable-work related knowledge and experience by utilizing and implementing the steps given in this lecture.

**Prerequisites: You must have access to or have installed in your lab the following: **

• Two Windows 2016 Servers with Active Directory installed and promoted to a domain controller (DNS installs automatically).
• Or a VM with the identical configuration.
• Don’t forget to download the supplemental information that I have supplied with this lecture.

**So what is conditional forwarding? And how is conditional forwarding used? **

**A conditional forwarder **is a DNS server on a network that forwards DNS queries for external DNS names according to specific domain names.

Here is a typical scenario:

Two companies have merged High Quality and United Support Services. Both companies wish to keep their AD infrastructure separate but need to share technical data. You are the lead DNS Administrator for United Support Services. The question is, how can you easily fix this problem? One method could be using conditional forwarders.

**Here is an overview on how this could work for you. **

• You would coordinate this effort with the DNS administrator from HQ
• The HQ admin will need the domain name (uss.com) and IP address of the DNS server that will be configured with the conditional forwarder.
• You will setup a conditional forwarder pointing at HQ.
• HQ will setup a conditional forwarder pointing at USS

**The Benefits of using Conditional Forwarding: **

• Improves name resolution for disjointed namespace which are separate forests or doma…
