[Zope] Bad Hostname with Zope 2.8.X on Windows

Hi all, I'm using Zope 2.8.0.b.1 on windows 2000. The problem is quite simple: when I start the zope server the hostname is 'Localhost' then it's impossible to connect the server remotely (i.e. by specifying the IP address of the server) I know that in version 2.7 this problem doesn't appear. When I launch zope 2.7 the hostname is 'MyMachineName' How to fix that? Which file should I update? Thank you Simon
