WMI Windows required ports

Discovering Windows hosts from a Windows based ITO server.

ITO relies on the Windows Management Interface (WMI), RPC, and DCOM to communicate from the ITO server to the target client so the following windows based ports are required for WMI based discovery.

DCOM uses dynamic port ranges to respond to communication requests from a source server:

Windows 2000, XP, and Server 2003:   ports 1025 to 5000

Windows 2008, Vista and later:   ports 49152 to 65535
