Task 11
You need to ensure that all DHCP clients that get an IP address from SRV1 will be configured to use DC1 as a DNS server.
One possible solution to ensure that all DHCP clients that get an IP address from SRV1 will be configured to use DC1 as a DNS server is to use the DHCP scope options. DHCP scope options are settings that apply to all DHCP clients that obtain an IP address from a specific scope. You can use the DHCP scope options to specify the DNS server IP address, as well as other parameters such as the default gateway, the domain name, and the DNS suffix. Here are the steps to configure the DHCP scope options on SRV1:
On SRV1, openDNS Managerfrom theAdministrative Toolsmenu or by typingdnsmgmt.mscin the Run box.
In the left pane, expand your DHCP server and click onIPv4.
In the right pane, right-click on the scope that you want to configure and selectProperties.
In theScope Propertiesdialog box, click on theDNStab.
Check the boxEnable DNS dynamic updates according to the settings below. This option allows the DHCP server to register and update the DNS records for the DHCP clients.
Select the optionAlways dynamically update DNS records. This option ensures that the DHCP server updates both the A and PTR records for the DHCP clients, regardless of whether they request or support dynamic updates.
Check the boxDiscard A and PTR records when lease is deleted. This option allows the DHCP server to delete the DNS records for the DHCP clients when their leases expire or are released.
Check the boxDynamically update DNS records for DHCP clients that do not request updates. This option allows the DHCP server to update the DNS records for the DHCP clients that do not support dynamic updates, such as legacy or non-Windows clients.
In theDNS serverssection, click on theAddbutton to add a new DNS server IP address.
In theAdd Serverdialog box, enter the IP address of DC1, which is the DNS server that you want to use for the DHCP clients, and clickAdd.
ClickOKto close theAdd Serverdialog box and return to theScope Propertiesdialog box.
ClickOKto apply the changes and close theScope Propertiesdialog box.
Now, all DHCP clients that get an IP address from SRV1 will be configured to use DC1 as a DNS server. You can verify the DNS configuration by using theipconfig /allcommand on a DHCP client computer and checking theDNS Serversentry. You can also check the DNS records for the DHCP clients by using theDNS Managerconsole on DC1.
