Configuring the Relay Server IIS Host for Load Balancing

Update the configuration of the IIS Web server used by relay server already deployed to the DMZ so that load balancing operates correctly.

• Configuring IIS for the Relay Server Load Balanced Environment
  Configure the IIS server that hosts relay server to work with Application Request Routing (ARR).
• Setting Up the IIS Web Server Farm
  Set up an IIS Web server farm to identify all IIS servers used to host relay servers on your network. Once the farm has been defined, you can balance loads among servers in this farm.
• Setting Up Application Request Routing Rules and Load Balance Policies
  Set up Application Request Routing (ARR) rules to provide load balancing for IIS servers used as relay server hosts. Use load balance policies to configure which algorithm the ARR server should use.
