What version of Zope (I am assuming Zope 2.7.x)?

Can you share the contents of the <http_server> section of your 
zope.conf file?

Can you connect to it at 'http://localhost:8080/' from the box where it 
is running?  We've had at least one bug where having just the port 
number in the config file resulted in different behavior on Linux vs. 
Windows:  on the Linux machine, Zope bound to the port on *all* 
interfaces, while on Windows, it bound only to one interface (localhost, 
I think).
