Step 6: Add a Host (A) and Alias (CNAME) Resource Record to Corporate DNS for the Federation Service and DRS
You must add the following resource records to corporate DNS for your federation service and Device Registration Service that you configured in previous steps:
| Entry | Type | Address |
|---|---|---|
federation_service_name |
A |
IP address of the AD FS server |
enterpriseregistration |
Alias (CNAME) |
federation_server_name.contoso.com |
You can use the following procedure to add a host (A) and Alias (CNAME) resource records to corporate DNS for federation server and the device registration service.
Membership in Administrators, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).
To add a host (A) and alias (CNAME) resource records to DNS for your Federation Server
On you domain controller, from Server Manager, from the Tools menu, click DNS to open the DNS snap-in.
In the console tree, expand the domain_controller_name node, expand Forward Lookup Zones, right-click domain_name, and then click New Host (A or AAAA).
In Name, type the name you will use for your AD FS farm.
In IP address, type the IP address of your federation server. Click Add Host.
Right-click the domain_name node, and then click New Alias (CNAME).
In the New Resource Record dialog box, type enterpriseregistration in the Alias name box.
In the Fully Qualified Domain Name (FQDN) of the target host box, type federation_service_farm_name.domain_name.com and click OK.
Important
In a real world deployment, if your company has multiple UPN suffixes, you must create multiple CNAME records for each of those UPN suffixes in DNS.
