Set Agent Proxy Default setting – SCOM 2012 R2

Run this on any server that has the SCOM Console installed.

add-pssnapin "Microsoft.EnterpriseManagement.OperationsManager.Client";
 new-managementGroupConnection -ConnectionString:scomserver.domain.com;
 set-location "OperationsManagerMonitoring::";
 Set-DefaultSetting -Name HealthServiceProxyingEnabled -Value True

Totally stole this from the SCOM aficionado – Kevin Holman. His post is here
