WMI requirements
The following table lists the WMI requirements required by systems running Microsoft® Windows® operating systems to establish a successful WMI connection with a remote system.

WMI technology is based on DCOM / Remote Procedure Call (DCOM/RPC) communication. DCOM/RPC allocates the ports used by the server within a dynamic port range—typically between ports 1024 and 65536. To configure these ports using Windows Firewall on your managed computers, enable the Inbound Rules in the WMI group. See the Microsoft operating system documentation for details.
Ports 135, 445, and dynamic ports 1024 to 65536 must be open between Patch Manager and the remote system. See Port requirements for all SolarWinds products to review all Patch Manager ports.
