You can't run the XSI without the server license (SPM). The server license is a separate software that you install, and it holds the license of XSI. When you launch XSI, the license server must be running, otherwise XSI won't launch.
To install it, read the licensing manual.
Finally, you can find the name of your machine by going on the desktop, right-click on My Comptuer, choose Properties, Network Identification tab. What is typed next to Full computer name is the name of your machine.
Hope this helps
