Hi hellomogen, Thanks for your post. In certain scenarios, only a limited set of TCP/IP ports are allowed through a hardware firewall. Administrators must ensure that WMI (which relies on RPC over TCP/IP) is allowed through these types of firewalls. By default, the WMI port is a dynamically allocated random port above 1024. The following Microsoft knowledge article discusses how administrators can limit the range of dynamically allocated ports. Limiting the range of dynamically allocated ports is useful if, for example, the hardware firewall only allows traffic in a certain range of ports. For more info, see How to configure RPC dynamic port allocation to work with firewalls.
