Conguring 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 dierent systems and congure 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 congure 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 dierent WDM Management servers.
Prerequisites
Before you set up the ARR Proxy server, you must make sure of the following:
