Install Guide

The communication between the ARR Proxy Server and the WDM Management Servers must be on HTTPS protocol. Hence, you must
disable the SSL o-loading feature and congure SSL on the individual WDM Management Servers. If you use a self-signed certicate
setting up SSL on the WDM Management Server, then import this certicate to the Trusted Root Certicate Authorities store for a local
computer on the ARR Proxy Server by following the steps available on support.microsoft.com. IIS ARR requires a trusted certicate to exist
between ARR and the back end server it connects to; otherwise it will return a security error and refuse to route to the back-end server.

4 Select Health Test.
a Enter the fully qualied domain name (FQDN) of the ARR proxy server in the URL eld. The value should be : https://<Proxy
IP|FQDN>/hapi/ping. This is the URL, which ARR uses to send requests to the WDM Management Server to check the Health
for a particular server farm.
b Set the Interval time period after which the ARR Health Test repeats the Health Check. The default is 30 seconds. You can set it
to 180 seconds.
c Set the time out period of the URL you specied. This is the time period during which if the server does not respond, it is
marked as
Unhealthy.
