ok, i'm looking at the properties tab of the website that i created in IIS, when i created this website i did not include a Host Header because that field was optional, i decided that i would like to have a header, so under website identification i click the Advance button, highlight my ip address, select edit, in the add/web site identification dialog box in the Host Header Value texbox i put in the name of my site and select ok.
i'm not trying to setup the headers through the FrontPage Server Extensions. everytime i set up these headers it seems to somehow "knock out" the site..
