Give Preference to DNS Names When Omnissa Horizon Connection Server Returns Address Information

By default, when sending the addresses of desktop machines and RDS hosts to clients and gateways, Horizon Connection Server gives preference to IP addresses. You can change this default behavior with an LDAP attribute that tells Horizon Connection Server to give preference to DNS names. In certain environments, having Horizon Connection Server return DNS names to clients and gateways can provide additional flexibility in designing a network infrastructure.

The LDAP attribute affects clients that run Omnissa Horizon Client for Windows, Omnissa Horizon Web Client, and secure gateways on Horizon Connection Server instances.

Note: Horizon Web Client is available with Horizon 8 versions 2412 and later. For Horizon 8 versions 2406 and earlier, Horizon Web Client is called "HTML Access." This documentation page uses the name "Horizon Web Client" to refer to both Horizon Web Client and HTML Access.

Prerequisites

See the Microsoft TechNet Web site for information on how to use the ADSI Edit utility on your Windows Server operating system version.

Procedure

1. Start the ADSI Edit utility on your Horizon Connection Server computer.

2. In the console tree, select Connect to.

3. In the Select or type a Distinguished Name or Naming Context text box, type the Horizon distinguished name appropriate for your deployment's version.

   Note: Starting with version 2503, this name is DC=vdi,DC=horizon,DC=internal.

4. In the Select or type a domain or server text box, select or type localhost:389 or the fully qualified domain name (FQDN) of the Horizon Connection Server computer followed by port 389.

   For example: localhost:389 or mycomputer.mydomain.com:389

5. On the object OU=Properties > OU=Global > CN=Common, set the pae-PreferDNS attribute value to 1.

   When this attribute is set to 1, Horizon Connection Server returns a DNS name, if a DNS name is available and the recipient supports name resolution. Otherwise, Horizon Connection Server returns an IP address, if an IP address of the correct type for your environment (IPv4 or IPv6) is available.

   When this attribute is not set or is set to 0, Horizon Connection Server returns an IP address, if an IP address of the correct type is available. Otherwise, an IP address compatibility error is returned.
