Configuring DNS for TS Session Broker Load Balancing

  • Article

Applies To: Windows Server 2008

To configure DNS round robin entries for TS Session Broker Load Balancing, you must map the IP address of each terminal server in the farm to the terminal server farm name in DNS.

The following procedure provides the steps to configure DNS on a Windows Server 2008-based domain controller.

You must be a member of the Domain Admins, Enterprise Admins, or the DnsAdmins group to complete this procedure.

To add DNS entries for each terminal server in the farm

  1. Click Start, point to Administrative Tools, and then click DNS.

  2. Expand the server name, expand Forward Lookup Zones, expand the domain name, and then click the appropriate zone.

  3. Right-click the zone, and then click New Host (A or AAAA).

  4. In the Name (uses parent domain name if blank) box, type the terminal server farm name.

    The farm name is the virtual name that clients will use to connect to the terminal server farm. For management purposes, it is recommended that you use the same farm name that you specified when you configured the terminal servers to join a farm in TS Session Broker.

Important

Do not use the name of an existing server for the farm name.

  1. In the IP address box, type the IP address of a terminal server in the farm.

  2. Click Add Host, and then click OK when you receive the message that the host record was successfully created.

  3. Repeat steps three through six for each terminal server in the farm.

Important

You must specify the same farm name in the Name (uses parent domain name if blank) box for each DNS entry. 

For example, if you have three terminal servers in a farm named FARM1, with IP addresses of 192.168.1.20, 192.168.1.21, and 192.168.1.22, the entries would look similar to the following:

**Farm1 Host(A) 192.168.1.20**

**Farm1 Host(A) 192.168.1.21**

**Farm1 Host(A) 192.168.1.22**
  1. When you finish, click Done.

Note

By default, a DNS round robin entry is enabled when using DNS on a Windows Server 2008-based domain controller. The Enable round robin setting is available on the Advanced tab when you view the properties of the server in DNS.
