Create a TS Gateway Server Farm
Applies To: Windows Server 2008
TS Gateway uses two connections for each client session: one for inbound traffic and one for outbound traffic. This procedure is required to ensure that if a load balancer distributes each connection to a different TS Gateway server, the traffic from both connections will be redirected to the same TS Gateway server.
Important
You must already have load balancing configured before completing this procedure. TS Gateway does not perform load balancing itself. This procedure only ensures that TS Gateway will function correctly with a load-balancing solution that is already in place.
Membership in the local Administrators group, or equivalent, on the TS Gateway server that you plan to configure, 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).
Important
The TS Gateway servers that you add to the TS Gateway server farm must be domain members, and they must each have identical authorization policies (Terminal Services connection authorization policies and Terminal Services resource authorization policies).
To create a TS Gateway server farm
Open TS Gateway Manager.
In the console tree, click to select the node that represents your TS Gateway server, which is named for the computer on which the TS Gateway server is running.
In the results pane, under Configuration Status, click Add TS Gateway server farm members (if you have already added one or more TS Gateway servers to the server farm, the hyperlink title will appear as View TS Gateway server farm members).
On the Server Farm tab, in the TS Gateway server farm member box, type the name of the TS Gateway server that you want to add to the farm, and then click Add. Keep in mind that you can specify a NetBIOS name, a fully qualified domain name (FQDN), or an IP address for each TS Gateway server when you add it to the farm, but the name must match the name for the TS Gateway server that is used in Active Directory Domain Services.
After you click Add, the TS Gateway server name will appear under TS Gateway server farm status.
Repeat step 4 as needed, making sure that you add the names of all the other members of the TS Gateway server farm, and that you include the name of the local TS Gateway server. The list of TS Gateway server farm members must be identical on each TS Gateway server in the farm.
Click OK.
Additional considerations
TS Gateway will interoperate with Network Load Balancing or non-Microsoft load-balancing devices for load balancing.
In a load-balanced environment, TS Gateway servers are grouped into farms, with each farm being represented to Terminal Services clients as a single computer name with one IP address.
