Enabling agents to connect from UNIX machines

When an agent connects to a monitored Windows® host from a UNIX® machine, you must make certain registry changes in order to allow the required COM services to run.

Disabling UAC

When an agent connects to a monitored Windows host from a UNIX machine, user access control (UAC) must also be disabled in order for WMI connections to succeed.

This requirement affects: Windows Vista, Windows Server 2008, and Windows 7.

Navigate to Control Panel > User Accounts and Family Safety > User Accounts > Change User Account Control Settings, and change the setting to Never Notify.
