Configuring WMI Access Remotely Using Group Policy

Configuring the Firewall for Windows Management Instrumentation (WMI) using Group Policy

You should not meet any difficulties when collecting the inventory data using WMI from domain computers. But unfortunately, problems occur sometimes. They can be caused by changing the security settings or by some other reason. If errors arise while the program is trying to access domain computers via WMI, the problem can be solved remotely with the help of the following instruction on using Group Policy settings.
