In this task, you will configure the primary and secondary DNS addresses for the virtual machine. This is not a firewall requirement.
In the Azure portal, navigate back to the AZ500LAB08 resource group.
On the AZ500LAB08 blade, in the list of resources, click the Srv-Work virtual machine.
On the Srv-Work blade, in the Settings section, click Networking.
On the Srv-Work | Networking blade, click the link next to the Network interface entry.
On the network interface blade, in the Settings section, click DNS servers, select the Custom option, add the two DNS servers referenced in the network rule: 209.244.0.3 and 209.244.0.4, and click Save to save the change.
Return to the Srv-Work virtual machine page.
Note: Wait for the update to complete.
Note: Updating the DNS servers for a network interface will automatically restart the virtual machine to which that interface is attached, and if applicable, any other virtual machines in the same availability set.
