Remote WMI Connection: How to enable or disable WMI Traffic Using Firewall UI

Featured-Image

Windows Management Instrumentation (WMI) is a collection of Microsoft specifications for configuring and managing devices and applications on a network using Windows computing systems. WMI informs users of the state of local or remote computer systems. WMI’s role is to enable administrators to manage various Windows operating environments, including remote computers. WMI settings for Windows Firewall only allow WMI connections, not other DCOM apps. An exception must be made in the firewall for WMI on the remote target computer. The WMI exception allows WMI to receive remote connections as well as asynchronous callbacks from Unsecapp.exe. To allow callbacks to succeed, a client application must explicitly add its own sink to the firewall exceptions.

Please see this detailed guide on Windows Management Instrumentation: WMI Commands.
