Allow WMI through Windows firewall
- All users can read WMI data on their local computer. For reading WMI data on a remote server, a connection needs to be made from the computer you have installed the software to the server that you are monitoring (target). If the target server is running Windows Firewall, then open a command prompt and run the following command on the target computer:netsh firewall set service RemoteAdmin enable
- Check if you can add a node. If you are still unable to add, complete the steps in the Enable DCOM calls on the remote machine section.
