During setup it asks you if you want to install multiple servers. If you selected No the first time, it’s a bit of a pain to go back and change it later. If this isn’t a production environment the easiest thing is to delete the current server (save the names.nsf, admin4.nsf, events4.nsf, server.id and admin.id) and reinstall and select Yes when it asks if you want to run multiple servers.

By the way, XP is not a supported OS for Domino.
