Proxy for cluster nodes

This post is part of the Failover Cluster Checklist series.

If you have to use a proxy server to reach the internet for patches etc from your datacenter, you should define a fixed proxy setting on your cluster nodes. If you do not, some installers will fail or complain about not being able to download the latest updates.

In internet explorer for the user you use during installation

From cmd or powershell for all users and programs without explicit proxy settings

Only complete this step if you get errors after setting proxy settings for the user. MSSQL cluster installations require this setting in some environments, and it is recommended for cluster aware updating.

netsh winhttp set proxy [proxy server name:port] bypass-list=”*.[AD domain fqdn];local”

Sample: netsh winhttp set proxy 192.168.34.2:8000 bypass-list=”*.fabrikam.com;local”
