[Zope] localhost:8080 not found on windows

Hi I have installed Zope and Plone on a windows business server. On trying to view http://localhost:8080/manage I am getting a 404 not found etc. The server is already running a webmail service, however nothing comes up for locahost or http://127.0.0.1. I've also tried using the IP address of the machine to access the interface with the same result. The IP address is available in web DNS. Does anyone have any ideas on how to get the zope/plone browser interface running at all? Thanks
