1. Shortened URL
For example, if you enter the following URL in the Add Site dialog: http://sitename.corporate.local/subsite/SitePages/Home.aspx, Briefcase is able to detect the root of the site for authentication. However, if you turn this URL into a shortened one, Briefcase is no longer able to detect the root and authentication will fail. Therefore if you want to create a shortened URL, you must amend the original URL to read as follows: http://sitename.corporate.local/subsite/

The SharePoint site should have the fully qualified URL added to the access modifiers.
http://pacificfinancial/Pages may need to be entered as
3.Site is not connectable
Contributor was able to connect to a web server but the SharePoint site with the specified URL was not found on this server.
