We've got a SharePoint Server 2007 with a web application, where the AAM Default Zone is set to http://portal.domain.com for the Internal network. Users can successfully access the portal by connecting to this URL on the Internal network.
To access SharePoint over the Internet, I've added another AAM, with https://portal.domain.com for the Internet Zone. After publishing SharePoint through ISA, external users are able to successfully access to the portal, using https only.
So far so good.
However, I've now change the Default Zone to https://portal.domain.com, to make use of SSL not only for external connections. Launching https://portal.domain.com on the Internal network brings up the first page using https. Following any links from the main page it falls back to http rather than using https consistently, with a 404 error "webpage cannot be found".
What am I missing to use https consistently for External and Internal connections?
I've tried the "Intranet" Zone mapping without luck. First page can be accessed via https://portal.domain.com but it then falls back to http and HTTP 404 Not Found.
I read the article and thought I'll just start from scratch again with removing SharePoint from IIS and its zones.
Basically I created a new web application, specifying https://portal as the Default Zone. However, first page works fine again but then falls back to http. When I point to a link on the main page it already shows the link as http://portal.domain.com/...
Rigth now, there is no zone defined with http://... I haven't created the SharePoint site myself so just wondering if the problem originates there?
