Hi alessio marziali,
Actually, the Sitefinity setup on Windows XP Pro (IIS5) box
should go smoothly. Therefore, you are not seeing articles on this topic.
Could you described the exact problem you have?
Does your installation completed successfully?
Can you open the Project Manager? If so, can you see the name of the impersonated windows user on the right top corner of the screen? Does this user has permissions to create virtual directories?
Can yo create a project?
