Hello, My apologies if this has been answered before, I have searched the archives. I am evaluating Zope as a content management system for websites I run at a college. We currently run IIS and MS Exchange on an NT server. What I would like to know is this... Eventually I will want to start using Zope to serve the site/s but I imaging I will need to change the port number so it runs from http://www.ourhost.com/ rather than http://www.ourhost.com:8080/ But I am worried that if I change this it will cause the exchange system to fail many of our users access their e-mail using the Exchange webmail system at http://www.ourpost.com/exchange Does anyone else using IIS and exchange have some guidance they can offer. Very impressed with Zope so far! Phil
