The machine name is different, but the SharePoint site is set to use a domain name that points at the server:
if I go to http://machinename.root.com, I get the IIS7 homepage
if I go to http://alias.root.com, I get the SharePoint homepage
When in SharePoint pages, I am always using URLs that begin with http://alias.root.com. I thought that "/" in a URL meant "use the current path but strip everything back to the first "/" ??
I am an adminsitrator on the site, and my user has access to all sub-sites, lists etc. I can access the list data when using the "http://" style webURL, so something different must be happening when I use "/"
Confused, but not that bothered since it works with the hard-coded "http://" URL...
