The DNS service for Services Manager provides Domain Name Service (DNS) hosting from the cloud. The DNS service requires no installation and uses a WMI connection to the DNS server.

When the DNS service is provisioned to a customer, the service provider creates the DNS zone(s) that the customer can then use to create subzones, if necessary. The DNS service is available at the customer level only. The service cannot be provisioned to a customer's users.

Customers provisioned with the DNS service can create and manage DNS records that are attached to zones. DNS Service Administrators can manage these records for the customer while Full Reseller Administrators can manage these records for sub-customers.

Different types of records can be attached to a zone. When a record is created, only the Time to Live (TTL) setting can be modified.

Supported software

The DNS service supports Windows (WMI) and BIND (UNIX) DNS.

Requirements

When configuring your DNS environment, perform the following actions:
  • On applicable firewalls, open DNS port (53) and RPC ports (various) bi-directionally between the DNS server(s) and both the Services Manager web and provisioning servers. RPC uses random ports above port 1056, therefore non-stateful inspection firewalls might require open ports above 1056.
  • Add the DNS service account used for provisioning to the local administrators group.
  • Ensure the computer name has a DNS suffix. If the DNS server is outside of the Services Manager domain, ensure the DNS suffix for the Services Manager domain is on the DNS server.
  • Ensure the DNS application has a zone for the DNS suffix.
  • User Access Control (UAC) must be removed from each DNS server.
  • Ensure the DNS zone has an A record. If the DNS server is outside of the Services Manager domain, ensure the A record is in the format dnsServerName.ServicesManagerDomain. For example, DNS01.cloudportal.com.
