Create an Alias (CNAME) Record in DNS for WEB1
Applies to: Windows Server (Semi-Annual Channel), Windows Server 2016
You can use this procedure to add an Alias canonical name (CNAME) resource record for your Web server to a zone in DNS on your domain controller. With CNAME records, you can use more than one name to point to a single host, making it easy to do such things as host both a File Transfer Protocol (FTP) server and a Web server on the same computer.
Because of this, you are free to use your Web server to host the certificate revocation list (CRL) for your certification authority (CA) as well as to perform additional services, such as FTP or Web server.
When you perform this procedure, replace Alias name and other variables with values that are appropriate for your deployment.
To perform this procedure, you must be a member of Domain Admins.
To add an alias (CNAME) resource record to a zone
To perform this procedure by using Windows PowerShell, see Add-DnsServerResourceRecordCName.
On DC1, in Server Manager, click Tools and then click DNS. The DNS Manager Microsoft Management Console (MMC) opens.
In the console tree, double-click Forward Lookup Zones, right-click the forward lookup zone where you want to add the Alias resource record, and then click New Alias (CNAME). The New Resource Record dialog box opens.
In Alias name, type the alias name pki.
When you type a value for Alias name, the Fully qualified domain name (FQDN) auto-fills in the dialog box. For example, if your alias name is "pki" and your domain is corp.contoso.com, the value pki.corp.contoso.com is auto-filled for you.
In Fully qualified domain name (FQDN) for target host, type the FQDN of your Web server. For example, if your Web server is named WEB1 and your domain is corp.contoso.com, type WEB1.corp.contoso.com.
Click OK to add the new record to the zone.
