When you install the System Center Virtual Machine Manager (VMM) server, you can assign some of the ports that it will use for communications and file transfers between the VMM components. While it is a best security practice to change the default ports, not all of the ports can be changed through VMM. The default settings for the ports are listed in the following table.
