Microsoft's Window Management Instrumentation (WMI) are conditions that consolidate the management of devices in a Microsoft Windows Network. Implementing WMI enables you to manage local and remote Microsoft Windows computers from a central server. EmpowerID uses WMI to manage windows services, application pools and file shares. This document provides instructions on how to configure WMI for use with EmpowerID.
Perform these procedures on any Microsoft Windows Servers that you wish to use to manage local users and groups.
