Configuring Load Balancing
When you use WDM to manage thin client devices in a very large enterprise environment, a single WDM
Management Server cannot scale up to manage the large number of devices. There could be problems or
delays in client check-ins, schedule execution, or real-time command execution.
Load balancing helps resolve these problems to a great extent. In this setup, you can install and run
multiple instances of WDM Management Servers on different systems and configure the load balancing
feature between them. WDM uses the Microsoft Application Request Routing (ARR) for IIS 7 feature to
perform load balancing between the management servers. This section describes how to setup and
configure load balancing.

Setting up the ARR Proxy Server
The Application Routing Request (ARR) Proxy server is the most important component of Load Balancing.
This server receives the requests from the thin client systems and routes them to the different WDM
Before you set up the ARR Proxy server, you must make sure of the following:
• The entire setup should be on Windows 2008 Server R2 or higher.
• Install all the components of WDM on one server.
