Q7300007 - What ports do I need to open in the firewall to enable communication between the ActiveXperts Network Monitor server (the Engine) and the ActiveXperts Network Monitor Manager?

Communication between Network Monitor Manager (the graphical application) and the ActiveXperts Network Monitor Engine service is based on a Windows share. You must allow Windows Sharing through the firewall.

Windows Sharing (or more correctly RPC/DCOM) uses TCP ports 135 and 445 as well as dynamically-assigned ports above 1024.

The best practice is to use a packet sniffer like the Microsoft Network Monitor or SolarWinds to see which ports are required.
