You have to configure any installed Windows Firewall to allow the Traverse WMI Query Daemon to retrieve WMI data from the host.
Resetting the firewall settings will enable the firewall regardless of the platform.
Note: In earlier versions of Windows XP/2000, Windows Firewall might be referred to as Internet Connection Firewall (ICF).
The Windows Firewall service and Distributed Component Object Model (DCOM) can cause access denied errors (such as an "RPC Server Unavailable" error - 0x800706ba) when remote computers and accounts used for remote connections are not properly configured.
When obtaining data from a remote computer, WMI must establish a DCOM connection from the system with the WMI Query Daemon to the remote system that you want to discover through the WMI Query Daemon.
You must properly configure the Windows Firewall and DCOM on the hosts you wish to monitor in order to successfully connect from the Traverse WMI Query Daemon.
You must configure the target server locally by either changing the Group Policy settings, executing NETSH commands, or executing a script locally. Windows Firewall does not support any remote configuration. The procedures below describe how to configure the Windows Firewall using NETSH commands and the Group Policy editor.
