Hi folks: I am wondering if someone might help share some info on getting a particular feature of Orchard to operate on a Winhost site. My new Winhost site has been running a test install of Orchard for about a week now. (Thank you support for your help!). I am running 1.7.2 and just enabled multi-tenant. I setup a host record tenant.mydomain.com and configured Orchard with the multi-tenant site and configured this first tenant according to the docs from Orchard. The host record points to the same IP as mydomain.com. When I open a browser, put in tenant.mydomain.com, I get: Web Page is Unavailable We are very sorry. The web page you are trying to reach is unavailable. Please contact the Website Administrator. We apologize for the inconvenience. It seems as if IIS is returning a generic error and Orchard is not kicking in at all. I was thinking may be it's a host header issue / configuration in IIS, but my remote IIS Manager doesn't have an option to look at bindings. Anyways, like I said, it does not look like IIS understands what to do with this DNS name. It gives the same error if I try to browse my working site by IP address instead of domain name. How can I manage the host headers that are allowed to be sent to the IIS site? Or is there some other issue?
