Active Administrator - Agent cannot be installed - WMI error (4219599)

Active Administrator - Agent cannot be installed - WMI error

When attempting to install the Active Administrator agent from the Collection Agents tab of the Active Administrator Server Manager, an error is encountered

"The auditing agent will not be installed onto the computer [Fully Qualified Domain Name (FQDN) of the target domain controller] because the operating system version information could not be obtained. This is most likely caused by either WMI being blocked or WMI has been disabled."

Ensure the DNS suffix for child domains is added to the NIC on the AA server:

1. Open the Microsoft Windows Control Panel on the server where Active Administrator is installed
2. Select ‘Local Area Connection’ and then the ‘Properties’ button
3. Select the properties of the IPV4 protocol
4. Select the ‘Advanced’ button and the DNS tab
5. Append the DNS suffixes of the domains in the correct order for discovery

If the issue persists, ensure the AA service account and the Agent account you specify both have local Administrator rights (member of Domain Admins or Builtin Administrator group in the domain) on each DC in the domain. Log in to the AA server as the AA Service account (and the agent account if different) and run wmimgmt.msc. Right-click WMI Control and select Connect to another computer. Right-click WMI Control again and select Properties. If the account has the correct permissions, the OS information should be returned. If there is an Access Denied error, correct the permissions so that the Service account and agent account can return the OS information through WMI.
